"Error: Unable to make thumbnail (0)"

Okay, I just installed Gallery yesterday for my web site, and everything works perfectly. Then I get to uploading images into an album and I get an error that says "Error: Unable to make thumbnail (0)". I have ImageMagick installed, so I'm not sure what's wrong. I enabled debug mode, and tried the upload in form mode.

This is the error message I get:

Processing status...

It's probably something I did wrong, but I am new to this stuff, so if anyone can help, that'd be great, thanks.

The following information is required to get an answer:
Get this information from the PHP diagnostic (in the configuration wizard).
Gallery URL (optional but very useful): http://otown.jetsue.com/gallery/
Gallery version: 1.5-RC1
Apache version: 1.3.33
PHP version (don't just say PHP 4, please): PHP v4.3.10
Graphics Toolkit: ImageMagick
Operating system: Windows XP
Web browser/version (if applicable): IE6

Ok, I got it to work, thanks a lot.

I have one other quick question, though. I've seen under the names of the albums on some galleries, there are descriptions of what the album is about. I tried that, but it put the description inside the album so you have to click on it first to see what the album is about. How can I make it under the album title so one wouldn't have to actually go into the album to find out what it's about?
