When uploading TNs or top images, there doesn't seem any reason for the follow on to be the opened article.  The Features page seems more logical.

Also, the upload top image page and TN page have no instructions as to size, I just know from experience that tops should be 225x130 and TNs 99x99, but I think that should be part of the instruction.

...unless you've automated the software to resize images to the proper size?  If so, have you added auto brightening and sharpening these tiny photos usually need?  I've been making them manually so I don't know what's up there.
