Not all of the forums allow you to upload images for us to store. Some do, for the specific purposes of what the forum is meant for.
For example, the "Films and Screenshots" forum allows you to upload files, but only for the purposes of showing films or screenshots people would like to see.
In the cases where the forum does not allow the data to be stored, you must use another host provider to store the data, then you can link to it from here.
