What iPad do you have? Since you show an iPad with iOS 5.1.1, is this an original iPad? If so, you cannot upgrade beyond iOS 5.1.1.
There is no way to install iOS except by download from the Apple servers. Another version you may come across is not supported by Apple and very likely corrupted and hacked.
