Preloading images to browser's cache

Hi,
I'm working on a flash gallery project where images are
loaded through xml file.I have some buttons in the gallery for
different categories of images to be shown. Is there a way to
preload images to browser's cache prior to them being called.?,I'm
using AS2.
Thanks in advance...

You can simply load images into an empty movieClip, off
stage.

Preload image alternative

I used to use DW preload images behavior (rarely):
<body onLoad="MM_preloadImages('images/progress.gif')">
but I just realized that the following technique is much
better (and does not require js):
<body>
<img src="images/progress.gif" style="display:none;">
Am I right? Or am I missing something...

The load time for either option would be the same.

This is complete misinformation, really.

Error: Unable to locate an image file browser...

I get the error below when I insert an image element and try to associate a picture to it by either double clicking it or using the browse button in the Draw palette.
I have looked in my install directory and the "FileSystemBrowser.dll" file is present as well as the "ImageFileBrowserIDL.dll" file, so what gives?

Hi,
you should be able to fix that problem by re-registering Designer file browser DLL.

OBIEE 11g: how to automate browser clearing cache

Hi,
We upgraded OBIEE 10g to 11g the implementation includes EBS SSO ( which works in 10g).
the SSO functions OK meaning when we login from ERP Bussiness selection responsibilities to the OBIEE dashboard page we can access it and the login succeed.
The thing is that when we change the responsibility to another responsibility the Application role of the user does not updated and the old role ( the user get again the first role that was assigned in the first login ) meaning the role was not changed with the new responsibility.
I think that browser cache find OBIEE session and connect to the session without call /* valueof(NQ_SESSION.ACF) */ APP_SESSION.validate_icx_session('valueof(NQ_SESSION.ICX_SESSION_COOKIE)')
So, to automate browser clearing cache ?
Thank you

Thank you Veeresh,
I think this situation is due to a feature of Weblogic
"+The browser caches user credentials and frequently re-sends them to the server automatically. This can give the appearance that WebLogic Server sessions are not being destroyed after logout or timeout. Depending on the browser, the credentials can be cached just for the current browser session, or across browser sessions.+"
[http://docs.oracle.com/cd/E23943_01/web.1111/e13711/thin_client.htm#i1033402].
I understand the advantage that helps to not make the login process more unnecessary. But I have to disable the feature, otherwise the end-user will not be able to change permission on BI /ERP responsibility and will have totally close the browser. The question is how to disable it (Weblogic feature) ?
Thank you,
Ark

Double clicking an image in Browser view

I see that the behavior for double clicking an image in Browser view has changed between Aperture 2 & 3. In version 2, double clicking an image would jump from Browser view to zoom in on that image in full screen mode. Now in version 3, double clicking just switches to that image in Viewer mode in the main window, without entering into full screen mode.
While I guess this change makes some sense given the changes to full screen mode in v.3, my old fingers have gotten used to doing things the old way. To recreate what I used to do in v.2 I need to double click, then hit 'F' to do to full screen mode and then do the reverse to get back where I started.
Is there anyway I can change this behavior to the old v.2 way? I see lots of ways to customize hotkeys and commands, but nothing to change behaviors for a double click.
Thanks!

I can't find anything, but I'm still finding my way around!
I don't think you need to double click and press F..... just pressing F should change views.
Another way is to drag the "Full Screen" icon into the toolbar, and you can just click that.

Windows 8.1 and Lenovo preloaded image - update to be available?

Hi,
I work for an organisation that buys a fair few Lenovo machines. We get them with whatever OS they are bundled with at the time and then install our own image. However, recent Lenovo machines seem to have had significant optimisations which can't be reinstated if you do a clean install, so we have been using the preloaded OS image as a base an deploying our applications on top.
Windows 8.1 looks like it may become suitable for wider use here, so I am wondering if an optimized Windows 8.1 preload will start to ship with Lenovo machines soon? And if the preload image might be available for customers who have a Windows 8 machine, to allow for a clean install without losing all the optimisations, so that we don't have to wait for the first Win8.1 machine to be delivered.
Thanks,
Richard

I think it's safe to say you'll start seeing Windows 8.1 preloaded system from Lenovo as soon as Windows 8.1 becomes generally available. And I think Microsoft has said this will happen sometime in October.
However Lenovo will not provide Windows 8.1 preloads for existing systems such as T430, W530, X230, etc. These systems will soon go end-of-life with the coming Haswell refresh. The Haswell systems will get Windows 8.1 preloads, but existing Ivy Bridge systems will not.
Having said that, I really don't understand what you mean about "significant optimisations which can't be reinstated if you do a clean install". Off the top of my head I can't think of anything that is preloaded that isn't available for download on our support website, except for some 3rd-party trial software like Norton, MS Office, and Absolute. Is there anything specific that you need help with recreating/reinstalling in your own image?

How to stop the Browser from caching my web pages

Hi There
Can anyone tell how to stop the browser from caching my jsp pages
I am using
<%response.setHeader("Cache-Control","no-cache");
response.setHeader("Pragma","no-cache");
response.setDateHeader ("Expires", 0);
%>
but this does not work anduser is able to go back to the previous page
which i dont want and i want the browser to display the message the page has expired
Help appreciated
Thanks
Mumtaz

response.setHeader("Cache-Control", "no-cache");
response.setHeader("Pragma", "no-cache");
response.setDateHeader("max-age", 0);
response.setDateHeader("Expires", 0);
I have cut paste the code from my jsp which is working. There is one additional line. I do not know if that is the cause but there is no harm in trying that out.

Image provided in server cache does not appear in Excel download

Hello WD Experts!
I have a Web Dynpo (ABAP) ALV table with material master data. One column contains the image of the product or a "sorry, no picture" image, if no specific material image exists.
The images are not available as MIME objects, hence I load the images from an external source and push them into the server cache using the method cl_http_server=>server_cache_upload( ... ). The lifetime for the cache is defined with 600. The "sorry, no picture" -image is a MIME object.
All works fine... except for the download to Excel. Only the "sorry, no picture" -image appears. The others gets replaced by a placeholder icon which looks similar to those frequently seen in emails or slow web pages.
Why don't the cached images get downloaded to Excel???
Best Regards
Bodo

I would imagine this is a limitation of the Excel converter functionality within the ALV. It is probably designed to only download images that come directly from the MIME repository. The logic between the two approaches would be very different. Images in the MIME repository can be read from the database using the MIME APIs. To read the images from the Server Cache, the ABAP program would have to make an HTTP request to the cache (using CL_HTTP_CLIENT). I'm guessing the convert logic simply doesn't do this.
The other option is - is your lifetime high enough? 600 seconds seems like it would be long enough - at least for a test - there is no guarentee that in a real application the user might not display the data for more than 10 minutes before downloading. Probably not your problem, but something you might still consider if you get this working.
My only suggestion is that you would have to create your own excel conversion instead of using the ALV one.

Ghost images in Browser windows

I now have may thousands of photos and iPhotos is struggling to cope. I am trying to use Aperture but find it very frustrating. Whenever I try and look at images on browser they are ghost images (just dotted lines around) and I can only see them if double click on ghost. This seems to happen whether or not I have imported the images into Aperture or left them where they are. Sometimes it says iPhoto original and shows nothing see attached screenshot
Any advice appreciated

Thanks

I have also tried "Generating Thumbnails" and "Updating Preview" Neither had any effect.

          p = tiffDecoder.getNumPages();
          for(int x=0;x<p;x++){
          RenderedImage tiffPage = tiffDecoder.decodeAsRenderedImage(x);
          ByteArrayOutputStream stream = new ByteArrayOutputStream();
     TIFFEncodeParam tiffOptions = new TIFFEncodeParam();
     // You may want to set compression or tile attributes on the     EncodeParam here
     RenderedOp l_return = JAI.create("encode", tiffPage, stream,"TIFF", tiffOptions);

Show image in browser

hi,
i am new in PHP and oracle. can i show image in browser using image path from database?

vikash wrote:
No, Actually I m putting the path of image in database in varchar2 and i want to show image in browser using this path...plz helpGotcha - that actually makes life a little easier...
What you'll want to do with PHP (I'll lay this out for you a bit - I don't have a code editor/environment handy at the moment..)
1) You'll retrieve your image path from the database. Note that this path has to be the 'web accessible path', not a full file system path. (e.g. if your "Web Root" is /var/http/www and the full file system path to your image is /var/http/www/images/myimage.png, then the image you should have in the database is /images/myimage.png. This could also be a relative image path, etc.)
2) Use your retrieved database path to insert into your HTML <img/> tag. If you have 'short tags' enabled, it should look something like this:
<img src="<?= $myImagePath ?>" />
That's the basics - is there anything here that sounds familiar?

Sending Image to Browser

Hello Guys !
I need to load TIFF Image on Browser. Before this I'm converting to JPEG format whitout saving image on disk, just sending it to browser. This is the point: how can I format image in HTML format ?
response.setContentType("image/jpeg");
        ServletOutputStream sos = response.getOutputStream();
        RenderedOp src = JAI.create("fileload", "g:\\java\\00000001.TIF");
        ImageEncoder encoder = ImageCodec.createImageEncoder("JPEG",sos,null);
        encoder.encode(src);Thanks !

OK ! Now I see. But I don't know how to do that.
I created a JSP FILE:
<%@page contentType="text/html"%>
<%@page pageEncoding="UTF-8"%>
<%@page import="obj.*"%>
<%
NewServlet objServlet = new NewServlet();
out.println("<img src=" + ?????????? + "/>");
%>
<html>
<head><title>Image View</title></head>
<body>
</body>
</html>And have a code in NewServlet:
protected void processRequest(HttpServletRequest request, HttpServletResponse response)
    throws ServletException, IOException {
        response.setContentType("image/jpeg");
        ServletOutputStream sos = response.getOutputStream();
        RenderedOp src = JAI.create("fileload", "g:\\java\\00000001.TIF");
        ImageEncoder encoder = ImageCodec.createImageEncoder("JPEG",sos,null);
        encoder.encode(src);
    }HOW CAN I LINK THE NEWSERVLET WITH JSP FILE ???
PS: I HOPE I'M NOT BORING YOU !!!!
THANKS !

Very freaky, image in browser is not what's displayed

I was planning on doing a little organization in Aperture, and it seemed images
were out of place, as not in the right album.
Then clicking on image in browser to move it, discovered it's not the same displayed is really weird.
I quit the application before adding any from memory card that I was about to load in.
I'm at a loss as to what to perform w/o messing up the whole thing.
If more details are needed, feel free to inquire.
Thanks

Wow, now that link was hidden therapy. What a Nice Tour.
The menu's language at Aperture are so tech writer challenged, for me anyway.
If I ever get around to writing a third party program or scrip,
I'd love to create an add on to take every drop down menu item and
create a hovered cloud explanation as to what's going to happen if it's clicked.
At 50 something, it would make my day.
Maybe loading Aperture on a separate drive, and just slam through the gears to see
what happens vs doing burn outs on existing image files.
The built in manual I'm afraid is not reader friendly.
Thanks Much.

Rotated images in browser view but correct in viewer

Aperture 3. In numerous projects when looking at images in browser view some (not all) of the images are rotated incorrectly and some look as though they have been stretched. If I click on one of these images it opensin the viewer mode rotated correctly. Why is this happening and how do i fix it? Many thanks

Preview uses the testing server. When you say it doesn't work what happens?

Lightbox image 100% browser height or width

Hello everybody,
I am new here but I have a question regarding the lightbox. I am searching for a way to show an image in a lightbox that presents the image 100% browser height or width. The lightbox in muse only can show an image in native format. So if the image is too large for the height or width of the browser, the image will be cropped.
Is there a widget or another way to make the image scale in a lightbox with the browser height and width?
I hope someone could help me with this.

You can use any other slide show with full width as because lightbox will show the original image centrally on screen.
Thanks,
Sanjit
