He's trying to play with the pixels only because he doesn't understand
file structure in general. If he can't see it, he dismisses it, so the
metainformation is not considered. Why he's now fixated on images is
anyone's guess; mine is that its a lame attempt to encrypt binary files
(see below).
Simply put, if he can't see it, he doesn't understand it, so when
encrypting plainTEXT he encrypts only ASCII (printable subset), thus
wrecking the file structure by losing newlines, tabs etc.
Its been explained to him many times before, but he just doesn't
"get" that he needs to encrypt 8-bit bytes while ignoring file
structure.
