These forums used to have some of the more advanced functionality, such as the allowance of HTML code, but due to misuse it was removed. That's a good part of the reason (along with storage, depending on how the system was set up) we can't insert photos into a message either. However, there is a way to still show your images. We suggest using a free service such as ImageShack to host your image, then post the link to the image here. This is of particular help when you need to include the screenshot of a problem you're experiencing.
