Dear colleagues

I want to ask, where can I obtain the original versions of classic photos that are traditionally used for image encryption?

Examples include the Lenna figure, vegetables, baboon, cameraman, rice, etc.

Is there any source to get all such images, and maybe try out new ones, that aren't bound by any copyright.

Apart from the above, I want to see if there are any copyright free images of other types, like fingerprints, x-ray images, satelite images, that can be used as examples in image encryption papers.
