some versions of IE will launch some code when opening a JPG that would
overflow a buffer. a properly constructed JPG file would place code in the
overflow that could execute and do anything that IE was privilege to do,
i.e. anything.

Filters don't know nothin' but they block everything. I remember a rumor
from about 5 years ago that Jpegs could carry
viruses, (no explanation of how they could operate or spread), the
administrators of the CSC wan decided to block all Jpegs
from being downloaded system wide. It crippled web use including our own
internal web sites... (They used the same warning
message that "inappropriate" web sites displayed, it was "fun").
