Which Script is Imgkid.com Using?

Hello Guys,

Does any of you guys know which script imgkid.com is using? if not is there some way to figure it out? i checked the source code of this site, there is no where mention of which script this site is using also, also i do believe this is some paid script cause there are quite a few sites out there which are exactly like this one, same design and everything ...

If anyone knows about this script or can figure out which script is this, then please let me know, i would really appreciate that.

Thanks
