That's a clone in the most literal sens of the word, it has all of the same credits, behaviors, and references back to the original site. Almost like you just saved the script and changed the file path then uploaded to your host.
Usually when someone is seeking a clone they want the same behavior but different enough to stand on its own. In this case I feel it's probably more likely for generating signature images rather than profile images so saying the image is too large to fit in FAs profile page is a little silly.
I have verified that the Site works without any external scripts. I turned off my net, opened the page (stored on my pc along with scripts) and converted pic to bb code. It worked fine. Tried with 4-5 pics.
You verified that javascript works the way it was intended?
All you did was a copy paste site, from what it looks like the OP wants it customized now or the ability to customize it.
