Frank and Ed,

Thanks very much for your helpful responses. Interesting that such files really exist.

Malignant image files exist on purpose. The intent is to crash software and take over computers. Image files are one of the best ways to do that.

Some of the people who craft these files seem to be in the genious category.

Bob
