Icon images not previewing file content

I installed Leopard on MacBook Pro and on a G5 iMac. On the latter computer, the desktop file icons (iWorks document and others) display a preview of the document, but on the MacBook Pro, the icons display an image of the application. Minor issue, but I would like to understand why.

Some possible answers.
Firstly, you have checked that the desktop folder and any other relevant folders on the offending machine have their view options set to show icon preview?
Secondly, some files are given icons by applications that do not create a preview. In these cases the preview creation can be triggered by deleting the existing icon in the getinfo window. (That will not be the problem with iwork however).
Thirdly the previews are graphics intensive and, particularly if there are a lot of them, the system has to display at once it can struggle (or sometimes if files are tossed quickly onto the desktop I have experienced the finder needing to be prompted to redraw the desktop before the preview icons appear). It may be that your MacBook's graphics card is not handling Leopard's graphics as well as it might.

Hi,
Please provide more information ... such as:
- What are you trying to do? e.g. "Trying to import images from CF Card I get this message"
- What PC are you using? e.g. "Mac, PC, memory etc"
It is quite a cryptic thread but it sounds like you are trying to import directly from a CF Card, if you are copy the images to the hard disk then import.

Images not previewing properly in Bridge CS4

I just did a reformat & reinstall of my whole system. I opened Bridge to get back to work and none of my images will preview accurately in Bridge. They just show as horizontal and vertical pixelated representations of the image. I did not have a problem with Bridge until after the reinstall. Anyone have any ideas?
System details: Dell Dimension 8250 (I know, it's a dionsaur, but it works...for now), Windows XP Pro SP3, 1.5gb ram, Intel P4 3.06GHz HT
Thanks, Dana

Hi Dana,
Which settings are you considering and what are the performance issues?
You can optimize for certain workflows that will adjust processor intensive work, such as only generating large previews when displayed. If you're strictly talking about video card accelerated features, I think it's more a matter of On or Off as opposed to performance tuning. I just did a quick look and with video card acceleration enabled, in Full Screen Preview you can pan the image at magnifications much smoother.

Add a button to activate or not preview file in the folder

Is there a way to do this thing?
I'd like to add a button at the top of the finder windows to quickly able or disable preview files in the specific folder.
Thanks
Massimiliano

Open a Finder window, select View->Customize Toolbar, and add QuickLook button to the toolbar. The only other way is to invoke CMD+J and turn off or on icon preview.

Home Screen icon "image not available"

This is a weird one, and I couldn't find it addressed on the discussions.
All of my webclips on my home screen auto-created their own icons based on the webpages except for one.
In the case of "Pop Candy" from USA Today (http://blogs.usatoday.com/popcandy/) the icon is simply a long horizontal graphic that says "image not available."
Is anyone else getting this weird icon? Is this a USA Today server issue or an iPhone issue?

Popcandy is apparently set up to redirect any failed image call (in this case "apple-touch-icon.jpg") to a typepad generic "image not available" gif, which is what you're getting. What is interesting is that iPhone is not supposed to load a gif and is supposed to crop images.
Basically you've discovered a bug which will forever be known as the FUG Bug, the Fenlyn Unauthorized GIF Bug. Congratulations on your discovery.

How to add do not read file content option inside File Adapter (Synch Read)

Hi,
Is there any way, that I can skip reading the file content inside file adapter with operation as Synchronous Read ( I just want to read the file name and directory and if the file name matches with the input variables then I have to delete the files, for this i am using FA with synch read operation, everything is fine like deletion, but it is reading the file content and storing it in DB, i dont want this) .

This will solve your problem.

Icon images not displayed on canvas in form developer

It seems I've got the opposite problem from all the postings regarding icons. I've read the white paper: "How To Deploy Icons" and tried both "documentbase" and "codebase" settings, and icons are displayed fine in both cases when I preview (run the form from Form Developer), but I cannot see the gif images on canvas in Forms Developer, whatever setting I choose.
I'm running DS 9.0.4 and the only specific thing is that my startup shortcut on my XME desktop is starting in a directory where we store our *.fmb *.fmx files (W:\ScreenDevelopement\... which is not default directory - when you run from Start -> Programs menu).
It is not a big deal (I guess I can live without having images on canvas), but I don't understand why something that should be fairly simple to setup is such a pain.
Thanks,
A.M.

No part of the picture is visible on canvas in Forms Developer, and neither UI_ICONS nor UI_ICON_EXTENSION is helping. It looks like Forms Developer is totally disconnected from the rest of the DS (run time), and cannot figure out where to look for the pictures. As I mentioned earlier, when I run the screen preview the pictures are visible.

Finder not displaying file contents

I have dropbox and configured it to show the icon on the tray over the left of my day/time. When I click onto the folder via Finder, I see the folder icon. The "Info" for this folder should allow me to read/write to the folder. However, when I ask to see the contents, I do not get a listing of the files within the folder. I am very frustrated since I have been struggling to resolve this configuration issue out on my own. It is most likely 'user issue' which led me here. However, I am at my ropes end. Can someone tell me how to fix this?

Your original post wat to ask to see what was in that folder. The command I gave was to show that. There is one finder invisible zero-length file in that folder named .com.apple.timemachine.supported which I believe means it can be uses as a TB backup.
If you want to always see these finder invisible files -- everywhere -- then follow the instructions in this article:
Show Hidden Files in Mac OS X
Now you are asking about the folder itself, i.e., what it's access is. I would think you would see that doing Get Info in the finder. But the terminal command to do it is similar to seeing the folder's contents:
ls -lde /Users/petesalcido/Documents/Dropbox/London\ and\ Paris\ Pics\ 2012
Just -lde instead of -la as the ls options (that's an "ell" in the -lde just like the ls).

Scene7 images not previewing in Dreamweaver

I am working with Dreamweaver CC 2014 on OSX and I would like to use Adobe Scene7 for hosting images in emails that my company sends out. However, I am running into a huge problem. The images do not show in preview nor live view. The only way to see them is by opening the html file in a browser.
The odd thing is, Scene7 is the only service that this occurs with. Other external images pull into to preview with any problems. I did check make sure that Display External Files is checked. Any help would be greatly appreciated.

Well, I don' t normally post the HTML email online, however,
for this one I did, just to check and see if that would make a
difference. It didn't. The link to my HTML email is:
HTML
email example
I have tried getting ideas from other forums and this seems
to be common, once you set absolute links, you cannot preview the
images in Dreamweaver anymore. Some people don't seem to mind and
others find it annoying (like me), I guess I will just have to get
used to it. The images are mostly jpgs created in Photoshop or
Illustrator, saved for web. All the images are uploaded to the
webserver.
In the local settings in the http box I now have:

Preview file contents ?

I recently upgraded to 10.8.3.
My older finder allowed me to hit space bar to preview most files without opening them in their native app.
Did this feature go away in 10.8.3 ?

Basically, delete the /Library/Preferences/com.apple.symbolichotkeys.plist file, then restart your computer.

PDF icon images appear on desktop, but not in folders?

I just updated to Windows 7. Before the update I could only view pdf icons on the desktop and inside folders would be a screenshot pdf icon image of the file. This was very helpful when using a lot of pdf files.
NOW, after installing Windows 7, I have the exact opposite. I can see PDF image icons on my desktop, but when I go into a folder, I get the standard Adobe pdf red-white icon (no image).
Has anyone experienced this? Ive googled this and Im not the only one with this problem. Has anyone found a fix for this?
Thanks
Update: I forgot to add that PowerPoint files, jpegs and bmp files still work and you can still see the preview images. Just not PDFs.

function(){return A.apply(null,[this].concat($A(arguments)))}

What happens if you open an older PDF in Acrobat and do a "save as"? Does the icon come back?
graffiti - thanks for the reply. I did as you suggested but it didnt work. Now some icons are showing up but I dont know why nor do I know if this is a adobe issue or a windows 7 issues. While googling it looks like each side is blaming the other. Here is a screen shot. Some icons appear and one does not. I opened it and re-saved it but still doesnt show a thumbnail.

Icon (ie: Illustrator files) content no longer viewable in Finder.

Icon content no longer viewable in Finder. - Anyone have this issue with CS4 and Leopard?
For example: Illustrator file not viewable in finder in Leopard. Interestingly, I seem to remember that when scrolling through Illustrator files in the finder with Tiger, Panther, etc, if you have the preview window active, at least with .AI files, you'd get a preview of the graphics and not the default AI (or EPS) icon. Now I don't get any preview. Any suggestions?
I'm not sure if this is an Adobe or Apple issue, but I'm really finding too many quirks and conflicts between CS4 and Leopard that weren't issues in older versions of either companies previous software (say, CS3 or CS2 and Tiger).

...though it’s shameful that the old adage “if it ain’t broke (using the finder to preview file contents) wasn’t followed by Adobe and/or Apple. Thanks for this!
No kidding...
FOR THOSE WHO CAN’T FIND THE QUICK LOOK FOLDER **
It’s in your main computer system LIBRARY. You can’t search for it successfully, but I found it there.
You can also add a folder to your User Library called Quick Look (I named mine Quicklook and it worked as advertised.) I added it there just in case something went awry. You can have the same folders that is in the System Library in your User Library. I do this so I wouldn't mess with the System. If it works without a problem, and want it system-wide, I move the items from the User Library to the System Library.

How to make it a default for all received messages to not preview the attachment but instead show the icon? (mac mail.app)

Hi
I am having trouble with large incoming mail attachments.
When I receive a large attachment (pDf) the useful mail preview feature attempts to show a preview of the attachment. Unfortunately this is causing a lot of trouble as some PDFs are extremely large and therefore take time to open/preview. If I right click the attachment and select view as icon, the problem with that specific message ceases as the attachment is no longer previewed.
How can I make it the default for all attachments in received messages to only be shown as a icon and not previewed?

In Terminal,
defaults write com.apple.mail DisableInlineAttachmentViewing -bool Yes

How to save an icon as a bitmap file in illustrator with transparency?

Hello I need help,
I don't normally work with bitmap files however I find myself in need to save out a set of icons in this particular format for a client to use with their own software on a pc. this software can only import/use .bmp files.
In my export options .bmp is an option but I am unable to save it out with a transparent background which is a big issue. The result is an icon with white background and I need it to be transparent.
I tried pasting these icons to photoshop but I only is a portable bitmap format in the "save as" menu which I don't think will work as it creates a .PMP file and I don't think it will work with client's software. I am on a mac, with illustrator CC as well as photoshop.
I would very much appreciate help with this, I have been trying to figure this out for 2 hours now. Thank you in advance.

When I have created bitmap icons in the past (used to work for a software company) I used to create them with either a icon creator tool (Axialis) or directly in photoshop.
For color depths 24 BPP or less, the transparency is coded by using a fixed color. Each pixel that have this exact color will be converted as transparent when the image is loaded in the toolbar. Usually, the color used is green RGB(0,255,0) or magenta RGB(255,0,255). The problem of this method is that if you use a pixel of that color in your icon image (not the background), it will be converted as transparent. The other issue is the poor quality of the borders (around the icons) because it does not permit smooth transparency. In other words, a pixel is either 100% transparent or 100% opaque, there is no variable transparency. It results in "aliasing" on borders for icons with rounded shapes.
This is an old technique so you will struggle to get the desired results but worth you having a look for "creating bmp icons with transparency" online.
