Unable to generate thumbnails

[Stijn Haezebrouck]

Using PGV 4.2.3 on Ubuntu 9.10
It seems that I am no longer able to generate thumbnail images (after reinstalling my server) for new media files.
- when uploading an image, the option "generate thumnail" is not available
- when browsing "manage media files (or mulitmedia)", and showing all the thumbs, there is no link for the media files for which the thumbnails are missing
-  when clicking "create missing thumbnails", the missing thumbnails are NOT created

Can someone help me figure out what the problem can be?

Thanks!!

Doubt that Ubuntu has anything to do with it.
Manage Gedcoms > Edit > Multimedia > Automatically generated thumbnails  < What's this setting? YES or No.

How much Memory for PGV?  How large are the main images? Generating thumbnails demands a huge amount of overhead as the originals are loaded into ram, then duplicated for resizing. PGV does not manage large images well and is not a proper vehicle for photo archiving and sharing. There are far better programs for that purpose.

OK, I found a solution to the problem myself :)

It seems that, to generate thumbnails, the php package "GD" is needed.
I installed it using "sudo apt-get install php5-gd"
After this I needed to restart the apache2 server "sudo /etc/init.d/apache2 restart"
After this, the thumbnail generation worked.

Hey Stephen, thanks for your reply.
As you can read above, I found that the GD package was missing.

I generally use small images, about 100 kb in size. This works fine with the thumnails. This way, I only need to create 1 web optimized image, instead of 2 (a larger one and a thumbnail).
