OT: TikiWiki Thumbnails

[jhall at vandaliamo.net]

Ladies and Gentlemen,

Please excuse the off topic post.

I have installed TikiWiki, but I have not been able to get the software to
generate thumbnails at all.  The images are always displayed at their
original size.

This happens with gd from the ports collection, or compiling from source. 
Any suggestions would be greatly appreciated.

Thanks,

Jay
