500 Error - internal server error

[breauxlg]

I have ispconfig2 running several sites, one of which is a drupal site. www.praisebandexchange.com. When I put images into the content, they don't show on the page, but when I copy the link to see where it's pointing, it is pointing to a valid image file on my server, i.e. http://www.praisebandexchange.com/si....thumbnail.jpg
If I paste that address directly into my address bar, I get a 500 error, internal server error. The Drupal forum guys are telling me it's my server setup. I guess that could be, but I have a joomla site that displays images just fine. Could I have screwed up just the drupal site with my ignorance? Are there some permissions that are wrong or something? I've been fighting this for a while. I would really, really appreciate some help. Thanks, Lynn

I just went into the ispconfig log file and this is what I get:
http://www.praisebandexchange.com|||...||70.164.60.23 - - [29/Nov/2009:11:06:17 -0600] "GET /sites/default/files/images/praiseband-header_0_1.thumbnail.jpg HTTP/1.1" 500 1215 "-" "Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 5.1; Trident/4.0; .NET CLR 2.0.50727; .NET CLR 3.0.04506.30; .NET CLR 3.0.04506.648; .NET CLR 3.5.21022; .NET CLR 1.1.4322; .NET CLR 3.0.4506.2152; .NET CLR 3.5.30729)"

I went into the web site log file and got this:
