Cannot insert a picture (image - BLOB) directly into a report field?

Hello
I am new to APEX and I am trying to create a table with an image together with an input form and an output report but I am having difficulty in displaying the image in the report field.
My work so far:
1 I am using APEX to generate a table with a BLOB, Filename and Last_Update_Date fields.
2 I have followed the article on the http://www.oracle.com/technology/obe/apex/apex31nf/apex31blob.htm.
3 The title is: 'Defining and Viewing BLOB Data in Oracle Application Express 3.1'
4 I have generated the table, form and report.
5 I have downloaded the image as an attachment and inline on the form Ok.
6 I have successfully downloaded an image on the report with the words image as a link in the report field. Note the http path is: http://glkas0892v.greenlnk.net:7777/pls/htmldbDEV/apex_util.get_blob_file?a=475&s=7094501042405784&p=3&d=1360784770040764381&i=1360783771822764369&p_pk1=123&p_pk2=&p_ck=2F17C4FBDE22B25A02026F67AB59D4F0&p_content_disposition=inline
7 I have unsuccessfully tried to insert the image directly into a report field itself. The report displays the picture as a symbol with a cross.
Note the http path is: http://glkas0892v.greenlnk.net:7777/pls/htmldbDEV/apex_util.get_blob?s=7094501042405784&a=475&c=1360779972416764351&p=2&k1=&k2=&ck=4BFA878ADD2028D2E9B127BB03F78B8D&rt=CR
7a I have reduced the size of the images to 20 by 30 pixels but no joy.
Conclusion
The only difference I can see is that in 6 the command in the path is apex_util.get_blob_file? But in 7, unsuccessful, the command in the path is apex_util.get_blob?
Please help me as there must be some one out there who has experienced the same situation.
Thanks
Brian

My colleague has found the answer. A known fault exists within APEX 3.1 in that the Blob declaration must be after the Last update declaration and then the image displays correctly on the report.

  • I cannot insert a graphic image in a new composition: win 7, tb 24

    At times when composing a new e-mail I cannot insert a graphic image in the message. I have tried both the Insert button and the Insert icon. This does not happen all the time; but, when it does happen I can't seem to make it work. My system is a Win 7 with Thunderbird 24.3.0.5. I have tried inserting different graphic images and have tried all combinations in the Image Properties pop-up window.
    I have closed and reopened Thunderbird. I have restarted my system. I have closed all windows except Thunderbird. Nothing helps. Help! Thank you, Bill Gray

    Bill Gray here again. I find that if I open another Write window, then copy/paste my entire e-mail from the initial window -- I can insert graphics into the new window.
    What happens in Thunderbird to make this happen? This has happened a number of times. But, at least now I know that I can open a new Write window and get around the problem. Yet, I am still stuck with the nagging question: Why does this happen?
    Thank you and God bless, Bill Gray

  • Is there some way to import image files directly into an open document?

    Is there some way of importing a series of image files, say jpegs, directly into an open document, rather than having to open all the image files and having to drag and drop each individual one into the open document? Specifically, I'm a dentist and I often get digital xray images emailed to me from other offices. But they come as 16 or 18 individual image files and I have to put them into a virtual "xray mount", so I can view them all at once, rather than having to open all the images and toggle among them. So I open a blank document in PS (CS4), then I navigate to the folder containing all the image files I received, select all of them and open them all. Back in PS, I now have to select each image tab and drag the image into the blank "mount" and close the image. That new image then becomes its own layer in the "mount" document. But I have to repeat this 18 times for each patient! I was thinking if there was a way to open the new "mount" document then select all the image files and somehow "import" all the image files directly into document - essentially "automate" the process - that'd save me BOATLOADS of time and aggravation! Anyone out there have any suggestions? Thanks alot!! Dr. G.

    Thanks, Curt! When u say "animate" do u mean File | Automate...? Inside Automate, I can't find "Make Frames from Layers"...if you do mean "Animate" I can't find that menu. Zeno replied with a BRILLIANT clarification:
    <<Yes, but after you've got all your images as layers in a new document you can simply Select->All Layers and then drag them all to your document in one fell swoop.>>
    I tried that and it works like a charm! I select all 20 layers in the new document that "stacking" creates and just drag them all onto the virtual "mount" document. That's it! Then I just move each of these layers around as I would otherwise...it's just 1 click and 1 drag/drop. Unless someone comes up with a way to actually "import" all the images directly into the "mount" document, I think this appears to be the most efficient route to follow.
    I really appreciate your guys' assistance! It's so great that you guys monitor the forum and help us out with our Photoshop problems! What an awesome program it is, right?

  • Is there a way to import data from a specific text field in a PDF form directly into a text field in a different PDF?

    I know you can import form data from an .fdf file. Is there a way to import a specific value from that .fdf file into a text field in a separate pdf form?

    So I want the FDF to export every time the user saves or closes the PDF. Then I want the import to happen every time the user opens the PDF. That being said, this all has to work with Adobe Reader. If this is possible in anyway, I'd manage this would require some time of script. Any thoughts?

  • How to import pictures from Filesystem directly into subcatagory

    Until now I import pictures via the File Menue into the "big pot". Then I try to find the files in this "big pot" and draw it by drag/drop into the desired catagory/sub - sub - sub ..... catagory. It is not easy to find such imported files among several 1000 pictures especially if they have different dates. So is it possible to import selected files directly from the filesystem into a subcategory.

  • Cannot paste any online pictures from any websites into word/powerpoint/onenote 2013

    I cannot paste any pictures/ images copied from any websites into word, powerpoint and onenote.
    Now, i am so stressful because this strange problem occurs with both versions of Microsoft Office (2010 and 2013). I had updated the Microsoft Office from 2010 to 2013
    with the hope that this problem will be solved in 2013 version but I was so disappointed. I was so addicted to onenote and cannot live without onenote. In the past, I always used onenote to store countless handmade-creating articles and so many other information
    found on websites and other resources by simply copying (Ctrl + C) and pasting (Ctrl + V) them into onenote without any problems.
    This strange problem has occurred and resisted approximate 2 months. Now I am almost going insane. I am longing for help, any help from the online community. Please!
    I will describe the problem in more details.
    -My laptop was Asus N550JV, and it was installed only one operating system: Window 8 single language by manufacturer. Nothing such as virtual machine or multiple operating
    systems in this laptop.
    -This problem occurred with all websites, not only with a certain website or a specific website.
    -It occurred with all of my latest-updated web-browsers, including firefox, internet explorer (which was pre-installed by factory in my window 8), opera, safari, chrome.
    -Despite of using whatever web-browsers listed above, although the whole articles (text and pictures) on these websites were copied, however there was only text pasted
    successfully, excluding pictures.
    -Pictures/ images were not pasted together with text. The onenote/word/powerpoint only shows a blank space where the picture should be in. If I click on this blank space,
    a frame will appear covering this blank space inside, and the url address of this picture was shown. The
    “drawing tools”
    tab appeared instead of “picture tools”
    tab. I guessed the pasted pictures were considered as drawing objects, not as pictures.
    -After many unsuccessful attempts to solve this problem in Microsoft Office, some days ago I decided to install Open Office of Apache in the same laptop in order to make
    a control test between the two programs. I was successfully in copying and pasting text and pictures on many websites (using whatever web-browsers I am having) into text document of Open Office without any problems. Pasting pictures and text from websites
    into Open Office was successful, so that what the hell was happened with my Microsoft Office?
    -If I download or save the pictures found on websites to my laptop then using the
    “insert picture”
    function to insert these pictures into word/ppt/onenote, these pictures were inserted successfully without any problems.
    -Copying and pasting text and pictures from old articles stored in onenote to a newly created word document were successful without any problems. Copying and pasting text
    and pictures between word and word, onenote and onenote were successful without any problems.
    -It was concluded that this problem only occurred with online pictures pasted from websites, while inserting or pasting the downloaded pictures were successful
    without any problems.
    -My internet connection was not disrupted during copying and pasting processes.
    -My Canon laser printer only recognized and printed the text lines, there were only blank spaces in the places where the pictures should be in.
    During two months since having this problem, I have searched so many times in order to find a solution. All of solutions listed behind I already found on internet and tried
    them all but nothing worked! This problem still resisted in Microsoft Office 2013 and now I am so sad and tired because of it.
    List of solutions I found and tried but nothing worked:
    -Right-clicking then choose "paste option: keep source formatting”
    and choose “set as default paste option"
    -On the
    View tab of the Ribbon or on the status bar, choose
    Print Layout view, not Draft view.
    -Go to
    Office Button | Word Options | Advanced: Show document content and make sure that
    “Show drawings and text boxes on screen”
    is checked and that “Show picture placeholders”
    is not checked.
    -Go to
    Office Button | Word Options | Display: Printing options and make sure that
    “Print drawings created in Word”
    is checked.
    -On the
    Home tab of the Ribbon, locate the
    Paragraph group and click the dialog launcher arrow in the bottom right corner to open the
    Paragraph dialog; in that dialog, make sure that line spacing of the paragraph the picture is in is not set to an
    Exact value.
    -Paste the picture and immediately press
    Ctrl+Shift+F9 to unlink it. The picture will then be embedded in your document.
    -If you find that Word hangs when you try to paste, you can instead select
    Edit | Paste Special and choose “Device-independent Bitmap”
    instead of the default of “HTML format.”->
    I could not try this solution because my paste special options only had three choices: unformatted text, html format, unformatted unicode text.
    -Select File, Options, Advanced, then under
    Cut, Copy, Paste section set "insert/paste picture as”:
    tight/ inline with text/ through/ square/ top and bottom/ in front of text/ behind text… -> I have tried all
    choices but nothing worked.
    -Rename the Normal.dot or Normal.dotm global template file: run cmd.exe and type
    ren %userprofile%\AppData\Roaming\Microsoft\Templates\Normal.dotm OldNormal.dotm. Then type
    exit, and then press Enter. Or go to C:\Users\Home\AppData\Roaming\Microsoft\Templates to rename the Normal.dot/ Normal.dotm file manually.
    -Turn off the "Use draft quality" option:
    Click
    File, and then click Options. Click Advanced,
    Under Print, click to clear the Use draft quality check box. Click OK.
    -Change the view to:
    Print Layout/ Full Screen Reading/ Web Layout/ Print Preview
    For Word 2010-2013: Click File, and then click Print.
    -Check the box for
    “Print background colors and images”
    at File | Options | Display: Printing options.
    -Check the box for
    “Show background colors and images in Print Layout view”
    at File | Options | Advanced: Show document content.
    -Using repairing function to repair the Microsoft office 2013.
    Nothing worked! I have no clue of what have been happened with my Microsoft Office! Please help!
     I cannot upload a screenshot taken from my laptop into this forum. It said that
    body text cannot contain images or links until we are able to verify your account.

    To Scxy1234: I also don't know why my paste special options only had 3 choices excluding "device independent bitmap'
    To Steve Fan: I created the new second user account in my window 8. It was set as a standard account, not as administrator account as my first original user account. Specifically, i used the same email address with this forum account's to
    create this second user account. It means that the second user account in my laptop also was a Microsoft account.
    Can you guess what happened after i had logged in to the second user account? I opened some random websites by firefox, copied and pasted all text and pictures on these websites into a word document and onenote successfully without any problems!!!!
    I saved this word document and exported this onenote section to a Usb. After that, i switched from second standard user account to my window administrator account and opened the two files which were saved to Usb previously. They were opened and displayed
    normally as the same as what i previously had seen in the second user account, i.e. pasted text and pictures were displayed normally. However, when i opened the same web address again to copy the same text and pictures to word and onenote, there were only
    text lines pasted successfully, excluding pictures! This old strange problem happened again when using original administrator account for logging in window. In contrast, when using the second standard user account to log in window, copying and pasting text
    and online pictures of Microsoft office worked normally.
    I truly don't figure out the reason(s) caused this strange problem. I think my case is a special case because i tried all solutions other people had tried but nothing worked.
    Please help me!
    p/s: when i logged in the second standard user account, i opened the paste special options in word and there were only 3 choices under paste special options, excluding "device independent bitmap"

    Thanks for the quick response SKodidine.
    I actually figured out the problem I was having.  I was using jpeg images and after reading a few notes I tried using bitmap images and now all of my images show up.  BUT!
    I still have a problem.  For some reason all of my images show up in the report very small and pixilated.  When I try to expand the image they look horrible.  Also, the image file names and file type extensions show up beneath the image.  here is a screenshot of it.

  • Insert editable picture into PDF form?

    Good day,
    I am creating editable marketing flyers for a client.  I'm opening my PDF (originally created in Illustrator) in Acrobat and adding editable form feilds for the end user to add their contact information to each piece.  The enduser also wants to add a photo with their contact info.  Is there a way to create this as part of the form?  Ultimately, I'm wanting them to be able to insert a picture into a specified area and not have to resize the photo.  Is this possible in Acrobat professional?
    Any information would be greatly appreciated!  I'm working in CS3 and Acrobat 8, on a mac.
    Cheers,
    Lilly

    This post has been invaluable for me! Thanks for everyone input. I have used the event.target.buttonImportIcon(); javascript to create PDF's the user can import, and it works great. However I now have on last challenge and I am hoping someone on this forum can help out with. Is there anyway (with a little javascript on the button) to have the image the user uploads flip upside down? I have a document that needs to be folded in half, and it would be perfect if I could have the user upload the image to both buttons, but have one button flip the image upside down. I know I could have the user do that image flipping and re-saving on their own, but I am trying to simplify things. Any ideas here would be helpful.
    Thanks!

  • How do you insert a picture into another picture?

    How do you insert a picture into another picture.  For example, one person is missing from family photo & I'd like to insert that person's face.

    By using an external editor:
    In order of price here are some suggestions:
    Seashore (free)
    The Gimp (free)
    Graphic Coverter ($45 approx)
    Acorn ($50 approx)
    Pixelmator ($50 approx)
    Photoshop Elements ($75 approx)
    There are many, many other options. Search on MacUpdate. You can set Photoshop (or any image editor) as an external editor in iPhoto. (Preferences -> General -> Edit Photo: Choose from the Drop Down Menu.) This way, when you double click a pic to edit in iPhoto it will open automatically in Photoshop or your Image Editor, and when you save it it's sent back to iPhoto automatically. This is the only way that edits made in another application will be displayed in iPhoto.
