Cannot view thumbnail previews

I jus upgraded to Acrobat Pro but now I cannot view thumbnail previews of my PDF files in Windows Explorer.
How do I activate that back again?

This is ridiculous, as every other version of Photoshop has had it, and everyone is complaining.
It has been stated that this is an OS issue.

Have you taken the time to complain to your OS vendor yet?
Also: This is a user to user Forum, so you are not really addressing Adobe here, even though some Adobe employees thankfully drop by.

IMovie 8 I cannot view thumbnails

I am working in iMovie 8. Unfortunately, I cannot view thumbnails in the playback screen. Additionally, thumbnails are grey. Lastly, these thumbnails will not play. How do I fix this?

You may need to uninstall all previous versions of Adobe Flash Player, first, then reinstall the latest version to your Mac

Then, reinstall the latest version of Adobe Flash Player.

Cannot View Thumbnails in Full Screen

I imported 195 photo from my SD memory card to iphotos. I had a problem importing a .avi file to iphotos when I was importing the 195 photos which warranted a force quit to bypass the spinning beachball. The pictures all now show in Thumbnails and when i get info on the the total size is 175mb and all individual pictures size range from 600KB to 1MB. When I opt to view these pictures in full size i get a fullscreen exclamation mark.
These pictures are of a recent family trip to Disneyland and I am crossing my fingers that these can be retreaved so they can be view in full screen mode.
I would appreciate any assistance in finding a solution?

The ! or ? turns up when iPhoto loses the connection between the thumbnail in the iPhoto Window and the file it represents.
The most common cause of this is User Activity in the iPhoto Library Folder in the Finder.
Have you altered, moved or renamed anything in the iPhoto Library Folder?
If you haven't, then try rebuilding the database. Hold down the apple and option (or alt) keys while launching iPhoto. Use the resulting dialogue to rebuild.
However, that Force Quit may have damaged the iPhoto database, and if the above doesn't work, Try these in order - from best option on down...
1. Do you have an up-to-date back up? If so, try copy the library6.iphoto file from the back up to the iPhoto Library (Right Click -> Show Package Contents) allowing it to overwrite the damaged file.
2. Download iPhoto Library Manager and use its rebuild function. This will create a new library based on data in the albumdata.xml file. Not everything will be brought over - no slideshows, books or calendars, for instance - but it should get all your albums back.
3. If neither of these work then you'll need to create and populate a new library.
To create and populate a new library:
Note this will give you a working library with the same Events and pictures as before, however, you will lose your albums, keywords, modified versions, books, calendars etc.
In the iPhoto Preferences -> Events Uncheck the box at 'Imported Items from the Finder'
Move the iPhoto Library to the desktop
Launch iPhoto. It will ask if you wish to create a new Library. Say Yes.
Go into the iPhoto Library (Right Click -> Show Package Contents) on your desktop and find the Originals folder. From the Originals folder drag the individual Event Folders to the iPhoto Window and it will recreate them in the new library.
When you're sure all is well you can delete the iPhoto Library on your desktop.
In the future, in addition to your usual back up routine, you might like to make a copy of the library6.iPhoto file whenever you have made changes to the library as protection against database corruption.

Since upgrading to Lion, I can no longer view my previews in Aperture.

Since I updated to Lion, Aperture has been sluggish and annoying and keeps quitting on me...
However, the worst problem I have is that I cannot view the previews of most of my photos.
The files are all referenced and kept on an external hard drive.
I have checked to see if the preview files are in the Aperture library folder in my Pictures file (I looked in Show Contents...) and they all seem to be there.
When I open the projects in Aperture, the outline of the photos appear, but I can't see the images.
Does anyone have any idea why this would be and how to fix it?
Thanks!

As a start you should update your profile it still says you are using 10.6.1 and including the Aperture version would be a good thing also. So have you upgraded to 3.2.1 yet? If not you should.
As a start you should look at Aperture 3: Troubleshooting Basics and see i that helps.

Movie thumbnail previews in Coverflow and Grid view...not there

I'm using Snow Leopard and have both QT-X and QT 7 Pro on my MacBook Pro.
In Finder, I have a folder containing several movie types including mpeg, avi, mov, qt, m4v, mp4, flv and wmv
I've noticed that I don't see thumbnail previews for any of these movies and wondered if anybody else can see their thumbnails, either in Grid View or Coverflow
In 3-column view, the thumbail appears once the file is highlighted.
In iTunes, the thumbnail also appears (for those that can be added to the Library)
I also have the latest Perian and Flip4Mac apps installed.
I've tried re-launching Finder after deleting the com.apple.quicklook.plist file
Thanks

I also tried this (deleting the Quicklook cache) and no luck, still the same issue.
I did a clean installation and this works
However, I did again the installation and imported my USER profile in FULL via the assistant when you first configured Snow Leopard (using an FULL BACKUP copy and/or Time Machine Backup) and then problem reappears
I have reinstalled DivX, Desinstalled RealPlayer deinstalled Perian and still the same issue. I cannot see the Thumbnails or the Cover Flow of the video/movie file such MPG, MPG, AVI, WMV but it works for MP4 I have for my IPod
I finally gave up and left this last installation and I did not have the energy to migrate my data, emails, settngs, etc manually.
By the way, the upgrade from Leopard 10.5.8 towards Snow Leopard 10.6 was smooth but the performance was awful specially after installing 10.6.1. With the upgrade I had the same issue with my USER account or with any, NO THUMBSNAILs for most of my videos enough though they are played correctly in Quicktime and Quicklook....
Any help????

HT2506 After updating my system to Mountain Lion 10.8.2 I can no longer view videos on Facebook or other sites. The only one I can view videos on is youtube. I have downloaded Adobe Flash player and still no luck. I cannot even open Preview on my computer

After updating my system to Mountain Lion 10.8.2 I can no longer view videos on Facebook or other sites. The only one I can view videos on is youtube. I have downloaded Adobe Flash player and still no luck. I cannot even open Preview on my computer anymore. Any ideas would be helpful thanks

Merely clicking the Preview icon in the Dock doesn't cause it to open anything, unless you had one or more windows open the last time it quit.
If you're sure you've installed the latest version of Flash, take each of the following steps that you haven't already tried. After each step, relaunch Safari and test.
1. If you're getting a "blocked plug-in" error, triple-click the line below to select it:
/Library/Internet Plug-Ins Right-click or control-click the highlighted text and select
Services ▹ Open
from the contextual menu. A folder should open. If there is more than one item in the folder with the words "Flash Player" (not "flashplayer") in the name, open the respective Info windows, check the version numbers, and delete all except the latest. You may be prompted for your login password. If you get the same error after doing that, re-download and reinstall Flash. Download it from this page:
Adobe - Install Adobe Flash Player
Never download a Flash update from anywhere else.
2. If you get a "missing plug-in" error, select
Safari ▹ Preferences... ▹ Security
from the Safari menu bar and check the box marked Enable plug-ins.
3. Select
Safari ▹ Preferences... ▹ Extensions
from the Safari menu bar. If any extensions are installed, disable them.
4. In the Safari preference window, select
Privacy ▹ Remove All Website Data
Close the window. Then select
 ▹ System Preferences… ▹ Flash Player ▹ Advanced
and click Delete All. Close the preference pane.

"view content preview in thumbnails" option is not available in view settings for "finder" for one user

"view content preview in thumbnails" option is not available in view settings for "finder" for one user

I hope this discussion can be revived. I have the same problem. There seem to be quite a few Japanese sites that don't bother specifying their encoding. Perhaps they are older and from a time when it was not necessary to adhere to standards. Examples: http://www1.plala.or.jp/CUE/cave_yozawa.html, http://chigaku.web.fc2.com/saitama/sanchi/youzawa/youzawa.html. Happy to upload screenshots, but how?
Is there a way to tell Safari what encoding to use if the web page fails to do that?

Cannot view images using Preview

Happy New Year to all,
I cannot view .jpg files in Preview. I have .jpg files in various folders. If I:
a) Double click the .jpg file in Finder the Preview icon arrives in dock but no image is displayed.
or
b) Right click the .jpg file in Finder and select open with Preview the same as above happens.
If I then right click the Preview icon in dock I can see the image file name with a 'tick' mark next to it but no image is displayed.
The Preview help section in Apple is no help whatsoever. Any ideas ?
I am fairly new to the Mac so do not know if I have had this problem from day one, never tried before.
Thanks

Performance, minimum bandwidth, thumbnail previews for PDF and InDesign Files with web content viewer

Hi,
We are considering using DPS with a web content viewer for large PDFs and/or InDesign files. The client using a web viewer might have very limited bandwidth (some as low as 256Kbps). We ask:
1 - How well does the web viewer perform with very large PDFs and InDesign files (500 MB+) with limited bandwidth? Does the file stream in chunks and the PDF shows as soon as the first page or two are available, with the rest loading in the background, or does the entire file come down in one part and then shown?
2 - Can PDF and InDesign files support thumbnail previews? For example, one image per PDF page and user can scroll forward and back.
Your thoughts and comments are greatly appreciated.
Thanks!
-Stephen

Hi Stephen,
The way the web viewer works is that it converts the PDF/InDesign files to PNGs along with additional HTML assets. Assets are downloaded as they’re ready for a given page (e.g. first, page 1 is filled with its assets as they become available, then page 2, etc), so a reader wouldn’t need to wait for the entire article to load. The next few pages are also loaded in the background, so the reader wouldn’t be likely to notice lag as they flipped through pages to the next page after reading the current one. So the lag will depend on the size of an individual page.
For your question around thumbnails, the web viewer does not load a preview image so the reader would need to wait for the assets I described above to load.
Hope this helps...
Brian

Thumbnails/Previews not showing on tiffs viewed on Mac

I have a client who is asking me why the tiffs I'm supplying him with don't have thumbnails/previews. He's working an a Mac and has had to resave the files in order to create previews. I haven't been able to answer his question. Any takers? TIA. PShop CS4 / Windows XP.

Well, Photoshop does offer the ability to choose not to save thumbnails/previews... Check Edit - Preferences - File Handling. What's your setting?

IPhoto - cannot view multiple photos & my thumbnails are gone

When I open iPhoto, suddenly it is only showing 1 photo at a time; my multiview is completely gone, as is the scrollbar of thumbnails at the top. I tried going to View>Thumbnails, but the options under that are light gray and non-clickable.
I don't remember doing anything unusual recently, although iPhoto may have gotten an update a few days ago. Also, I should add that my MacBook's memory is pretty full; I'm not sure if that matters here or not.
Does anyone have any idea about how I can get my multiview & thumbnails back?
I-Cat

Thank you, TD! I noticed that right after I posted; I must have accidentally changed it without noticing. It does correct the problem. I also realized the thumbnail scrollbar is only in the editing stage. <shakes head> Okay, thank you. I will be back the next time I can't figure out a basic task.

I cannot view images in iphoto - only black screen

I had problems being unable to boot my iMac this week and ended up having to take it to the Apple store where they re-installed the operating system and all seemed fine. Now however, although I can view thumbnails in iPhoto, when I click on them I just get a black screen.
I've checked the images do still exist in the file folders and I had a slideshow running as a screensaver - this still shows the images but I cannot access them through iPhoto.
Can anyone help?
Thank you

There are several possible causes for the Black Screen issue
1. Permissions in the Library: Back Up and try rebuild the library: hold down the command and option (or alt) keys while launching iPhoto. Use the resulting dialogue to rebuild. Include the option to check and repair permissions.
2. Minor Database corruption: Back Up and try rebuild the library: hold down the command and option (or alt) keys while launching iPhoto. Use the resulting dialogue to rebuild.
3. A Damaged Photo: Select one of the affected photos in the iPhoto Window and right click on it. From the resulting menu select 'Show File (or 'Show Original File' if that's available). (On iPhoto 11 this option is under the File -> Reveal in Finder.) Will the file open in Preview? If not then the file is damaged. Time to restore from your back up.
4. A corrupted iPhoto Cache: Trash the com.apple.iPhoto folder from HD/Users/Your Name/Library/ Caches...
5. A corrupted preference file: Trash the com.apple.iPhoto.plist file from the HD/Users/ Your Name / library / preferences folder. (Remember you'll need to reset your User options afterwards. These include minor settings like the window colour and so on. Note: If you've moved your library you'll need to point iPhoto at it again.)
If none of these help:
As a Test:
Hold down the option (or alt) key key and launch iPhoto. From the resulting menu select 'Create Library'
Import a few pics into this new, blank library. Is the Problem repeated there?

Can't view thumbnails or edit recently uploaded photos.

In the last few rolls that I uploaded from my camera, the photos do not show up as thumbnails. I can see the photos if I choose "show file" but these can only be viewed in Preview and not in iPhoto. I have tried to copy them back into iPhoto but the program tells me that they are already in my iPhoto library.
Basically it seems the files are in my computer and iPhoto recognizes them as being in the library but I cannot view or edit these pictures. My other photos from past uploads are fine.
Any suggestions?

To repair disk permissions you launch Disk Utility (located in your Applications/Utiities folder), select your HD icon on the left and then click on Repair Disk Permissions.
Permissions are the Unix access control to files. it's what you can set manually on user files in the Info window. Disk Utility fixes and sets those parameters on system files and applications. It's wise to do so after any software installation or update.

How do I change the thumbnail preview picture

How do I change the thumbnail preview picture? I've got a 3d model and I want a particular view to be the thumbnail picture as well as the default view. I believe I've done that before but cannot figure out how I did it.

I'm working with pages that are comprised only one picture of a 3d object (a table). I really believe I was able to change the thumbnail to a particular point of view but can't remember how I did it. It's been so long that I can't remember, but I'm pretty sure I was able to.
