[opencms-dev] Help: Can't upload images of type ".gif" or".jpeg"

[Claus Priisholm]

When running tomcat through jsvc I've seen problems with classloader and 
images, so you may want to check that.

Seemingly after a while the classloader would complain that it cannot 
find some image-related class. I've seen it during "normal" operation, 
where the images on the site just started to go missing, but I would 
suspect a similar problem - once the classloader is confused or whatever 
is the problem - would cause problems for the upload as well (since it 
is trying to load the image to establish its size)
