Yeah, you can get YAM to do pretty much anything on any event. There's an "ARexx" page in the config section, and from there you can run any ARexx or AmigaDOS script for most events, but in the Notification section of the New Mail preferences page, you'll see an Execute Command option. Use this to run a picture viewer to show your picture. Even Multiview will do it, e.g. put Multiview WINDOW MyMailPic.iff in the box and see how you get on :-)
