I get this error when I try to upload any pictures at all. I'm using joomla 1.5, in legacy mode. Verified that my extensions (.jpg) are valid in RSGallery and the Joomla config. Attempts to upload .zip files don't work either.

Uploading documents into Docman work just fine (so I'm not thinking it's a transport or permissions issue)

I thought I would post here before rating this app on Joomla.org. It looks like a nice extension if it worked.

I'm a bit concerned at the numerous posts for help with no replies at all.
