Hi,

I have a Sharepoint slide library set up to show a thumbnail of the slide. The issue i am having is sometimes the thumbnail image show up as a red x instead of the actual picture. Other times the thumbnail image shows up fine. I tried different browsers, but can't seem to find the solution. Any idea what is causing this? I tried to right click and select "show picture" but that doesn't work. Thanks.

Hi Mariange,

do you have access to the SharePoint ULS logs? Perhaps you can find an error message in there.
Additional when you right click, show properties, whats the path/url of the image?

Normally thumbnails should be generated when you upload/publish a PPT and are stored in an "invisible" sub folder.

Perhaps you can also check the thumbnails through SharePoint designer, opening/connecting to your site and then using "All Files" in the left navigation.
Then navigate to your slide library. There you should see a folder "_t" which contains the thumbnails as JPGs.

I did connect to designer and under all files I do not see the "_t" folder. Is this folder in the main site or does each site collection have a "_t" folder?

Hi,
each Image Library and each Slide library should have the "_t" folder, as they are the ones where thumbnails are generated automatically.
Therefore under "All Files" you should open the folder of your slide library.

Hi,
do you have somehow a reproducible behavior?
If yes, can you install a tool named Fiddler (http://www.fiddler2.com)?
Fiddler acts as a proxy and you might get a little bit more info why the red X is shown (perhaps an authentication issue,...) because fiddler tracks all requests (and responses).
Then you might see if the return code has been a 404 (not found) or a 401 (authentication) or something else...

Which OS do you use (32/64bit)?
Which browser (32/64bit) do you use?
How many SharePoint web frontend server do you have?

Thanks and HTH
Rainer
