I am able to upload images in image galleries but neither the images, nor the thumbnails, are displayed.
The upload process seems to work — I can see the new files in the directory where they're stored (/tmp/ for now), and the image galleries list the uploaded files. (I have the same problem when images are stored in DB.)
I am running Apache2 2.0.49, PHP 4.3.6 with GD 2.0.22. The phpinfo() seems to show that GD is included OK.
Oddly, images uploaded to Wiki pages display just fine.
Has anyone seen this problem?
