Well, I cant understand polski so im willing to get help in english.
I was wondering is it possible to hide exe into *.jpg file?
If some on knows I would be very thankful to post information.
It is posible, but why you need this? You can hide any file in almost any image, but you will need something to extract it later - before you will be able to run it. (Easiest way - last significent byte in bmp, or uncompressed jpg)
