Images are not always 0 to 255. For example CT scan images are routinely int16 values, -32768 to +32767

I'm guessing you did not do a search of the File Exchange or you would not be asking this. Please click on this link: http://www.mathworks.com/matlabcentral/fileexchange/index?utf8=%E2%9C%93&term=encryption

It is a frustrating restriction, and often makes little sense, but it is the law of the USA.
Another note: authentication is considered to be different than encryption. So something like a well-hidden watermark to verify copyright is legal. The technologies for watermarking are essentially the same as steganography (hiding messages), so the legal boundaries are far from clear.

Any algorithm that can encrypt binary streams can be used to encrypt images.
Discussion of all the image encryption algorithms and their benefits and tradeoffs is beyond the scope of this resource.
