To clarify, I find it somewhat inconvenient when I want to see the original source thread but only the ip address or image itself is given as the source.
I agree with posting the source thread and try to do it myself (also makes it simpler checking for updates), but I think the problem is the uploading bookmark only uses the URL of the actual image, even if you set a source.
I'm somewhat new to uploading but I set the source after the image was uploaded rather than setting it when I uploaded it. I don't know if that makes a difference.
