"convert: no decode delegate for this image format&quot

I've been struggling for hours to get Gallery to create thumbnails - all to no avail. I've searched the forums and faq and followed instructions there, tested Imagemagick w/the diagnostic utility (and it works fine), and when I tried uploading an image in debug mode I get the following error messages. Can anyone help?

Here's my system info:

Gallery v1.4.4-pl4
Apache/1.3.33 (Unix)
PHP Version 4.3.9
ImageMagick 6.1.3

Here are the error messages:

- Adding db1.jpg
Resizing/compressing original image
No resizing required
File /home2/readyfor/public_html/albums/album35/db1.jpg type 2.

Executing:

'/usr/bin/convert' -quality 70 -size 100x100 +profile '*' '/home2/readyfor/public_html/albums/album35/db1.jpg' -geometry 100x100 '/home2/readyfor/public_html/albums/album35/db1.thumb.jpg'

Results:

none
