Last I knew U cant get malicious code from a pic of any type because no code can be executed from within a pic- they all need a viewer. This was confirmed by both Norton & CA when I was deciding to eliminate jpg, gof,tif,.. from my daily disk scan & realtime protection. That was 1.5 yrs ago.

What u want is Format > HTML but you *may* be able to catch virus from these in XP due to 'buffer overrun' vulnerabilities of XP

Comments/suggestions/corrections appreciated.
