Which image for steganography? -

-

which images suitable image steganography(storing behind image)?
in particular jpeg,bmp or tiff?
jpeg lossy possible lose data if hidden behind image?(using ls*strong text* technique)

technically of these can used, more see jpeg in use in wild. because steganography introducing imperfections in image hide message, imperfections less noticeable in lossy format, whereas if had off pixels in bitmapped image, 1 more notice discrepancy.

your question being lossy applies if tries resave image. example if opened image secret message hidden in in photoshop , saved out jpeg, image change , destroy message. not case when sending file via e-mail or web (except in case of isps implement jpeg compression speed browsing speeds slower connections dialup).
