Microsoft has officially accepted that 'image files' can contain virus due to a vulnerability of Windows.

http://www.microsoft.com/technet/sec...ry/912840.mspx

It means that you can get virus from image files that you receive by email or ... in a forum like this.

(In this forum nobody has published an image with virus but this could happen in any forum).

Some virus are currently using this feature:
Trojan-Downloader.Win32.Agent.abs
Trojan-Dropper.Win32.Small.zp,
Trojan.Win32.Small.ga
Trojan.Win32.Small.ev.
TROJ_NASCENE.A
TROJ_NASCENE.B
TROJ_NASCENE.C
