Uploads and Thumbnails

I continue to get errors attempting to upload image files. I will need to experiment to determine if it is all files or only images. Hopefully it is the latter. The installation instructions indicate that the thumbnail module Image::Magick is not required to upload but maybe I’m missing something somewhere else.
Update (11/5/2003): I’ve given up on this issue. I submitted a question to the MT support forum, bumped it up to the top of the list three times over the seven days without a response. I’m getting what I pay for out of that facility. Unfortunately, the common answers are what’s available. The uncommon or more time consuming issues are not going to get addressed through that resource. If I could find a way to get an error message produced that would be helpful. The “MT.CGI script produced no output” message is not going to get me help.
