Thumbnail Confusion

[dc41]

I'm confused about the thumbnail capability in the Document Library on Alfresco Share. I see there is a third party project for version 2.x, but I've also read that 3.x has the feature built in.

Should I see thumbnails in my Document Library after I upload a file? All I see is the little double-gear icon. Do I need to enable something?

Thanks!

V3.0 doesn't use the third-party extension.

You need to make sure ImageMagick and OpenOffice are installed for thumbnailing Office docs, etc. You also need pdf2swf for the web preview in details view.

Thanks for the response, Mike. I just want to make sure we're talking about the same thing.

I'm referring to the thumbnails you see as soon as you click on "Document Library". All my files have the double-gear symbol. If I click on the file (in this case a jpg), it brings up the detail page that allows me to zoom, full screen, etc. It works for .doc and .pdf files as well. I assume that means Imagemagick, openoffice, and pdf2swf are all working.

But there are only double-gear icons in the details view and generic doc-type icons in the simple view on the document library index page. Shouldn't these be replaced with generated thumbnails of the file itself?

Any suggestions?

Thanks!

Hi,
I had the same issue and resolved it by clicking refresh in browser when viewing doclib (in my case FF 3.3 seems to cache sth.).
You can use the nodebrowser to find out if your document has an attached thumbnail. All documents in doclib should have two childAssocs:
webpreview: the swf preview
doclib: the thumbnail displayed in doclib

The node browser doesn't show any children for any of the uploaded files, so I must have something set up incorrectly.

Here's the entire log from startup to uploading some files.

Could the head size max be causing any problems?

[mikeh]

It sounds like OpenOffice and pdf2swf are working ok, but possibly not ImageMagick.

Could you post the beginning of the alfresco.log file (i.e. the bit on server start)..?

Thanks,
Mike

I got it fixed! ImageMagick was installed and alfresco was pointed to the proper place. It just wasn't working.

So I "yum erased" the ImageMagick install that came from the Fedora 10 depo… then downloaded and installed the rpm from imagemagick.org.

Now thumbnails are working!  Thanks again for your help Mike.  :mrgreen:

Glad you got it sorted - thanks for the follow-up.
