|Well, considering you're dealing with a) teenagers and b) ones learning computer skills, you will probably find that they will quickly outsmart most standard methods of picture removal. (f/e: naming the pictures as ".txt" or some other extension would be the simplest. Hiding the pictures by appending them to an executable or data file also very easy to do). The most obvious removal method would simply look for all file extensions you listed and remove them (for each drive...):|
@echo off & setlocal
set list=*.jpg *.png *.gif *.bmp
del /s %list%
but I doubt such a simple approach will hold up for long against determined, horny, and probably intelligent young people. If you still want it, maybe me or someone else will throw one out there. I'm not well qualified for all the things you asked for, but I could make a simple script to start with.
ps: even looking for certain content, such as "JFIF", can readily be defeated by zipping and/or encrypting files.
pps: On the other hand, by posing a strategic technical challenge, you might accidentally spark some interest and uncover some real talent!
