Since a few month I have the following problem:

When I try to save an image from a website using the right mouse button and "save picture as", I can't save the picture in its original format (e.g. jpg, gif...). The only option I have is to save it as a BMP-file. I have tried to change the settings of the browser (IE 6.0) but didn't found anything to fix this problem.

Any help appreciated!
