keep in mind: whatever alteration to the original stego-ed file it will lose all the stego information. Be careful with that, otherwise you could lose the data you put inside. And always test your steganography.

This method is not to be used with only one copy.

Ah, I understand.

When I want to put such an image of my own somewhere public, it's a little suspicious if I post a large .tif file. People might immediately suspect it contains stego.

I was wondering if you had found an elegant way of losslessly compressing it to .jpg.

Best I could think of is ImageMagick's convert image.tif image.jp2 (where JPEG 2000 can contain losslessly compressed data), then rename to image.jpg.
