StegaLevel

Description

StegaLevel is a histogram-based form of steganography which hides one image within another. The secret image can be revealed by checking the Levels histogram in Photoshop. (Image > Adjustment > Levels...) I first came across this idea when a friend introduced me to the Ironic Sans blog.

Requirements

The image should be black on white and constructed from continuous vertical lines that are flush to the bottom.

Accepts JPEG, GIF, or PNG

Your Selected Image

Your StegaLevel Image

Drag this PNG image to your desktop, open it in Photoshop, then click Image > Adjustment > Levels... For some reason FireFox is being stupid about this. Try copying the image to the clipboard and pasting it into a new Photoshop document. Have fun passing along your secret messages.
