There are a number of ways of detecting the likelihood that an image has been altered to contain steganography. Many of the techniques that exist as available programs depend upon a knowledge of the file type (JPG, BMP, etc), and method used.

There are research efforts underway to generalize these types of estimates, but most are not ready for production use or are unavailable.

Furthermore, you mention "detect" but do you mean simply to "detect" or to "identify and isolate?"

The only sure-fired way to detect steganography is to have the original image with which to compare. Even with this, the techniques used to encrypt or obfuscate the actual stego content make it unlikely that you'll be able to determine what it is without a great deal of luck.

Perhaps you can describe what it is that you are trying to do.
