I'm pretty much sure that no. The uploader is not the default one that come with chevereto. The website doesn't use Chevereto Template system, and I could continue...
It could be chevereto... but it would be so much edited, that most of the chevereto code wouldn't be the same. So I would say no, but nothing is certain.
Nope and the whole system (at least the outputs) is pretty different. Since we can't see the code directly we can't say if part of the code was taken or not, impossible to tell... Sorry about that.
