If you set up an account on a website like
Photobucket, you can upload multiple images and recieve Image Codes for them.
This allows you to show the images on the forums, and more than just the 3 you can do with the upload file feature.
It will make it much easier to show off your images, and will make it easier for people to see your entire build.
From what little I can see, I like it.
I think it could do with some detail on top, though.
