no to images - unless you are going to spend a lot of time moderating them, not for inappropriateness but for stolen images ... i feel that it would reflect badly on a professional forum.
i also feel the image issue is connected to the outgoing links issue, it is also in the spirit of the web that you should link to content not copy it, so if links are allowed then the page an image is on should be linked to, rather than the image be uploaded to the WebmasterWorld server.
so: No to images
Yes to linking to images
