Can you be more specific? What kind of images (JPG, BMP, etc.).

There are no, practical, steganalysis tools which deal with all kinds of media. If you look at a current topic entitled "Hiding data from Encase" you'll find a lot of good references on steganalysis.

Helpful! roll

I have tried to use a few different tools but it appears that unless you use some of the common steg software (jsteg, jphide, camouflage etc) to hide your file the steganalysis ones wont find it. Is this the case for most?

Take a look at the following
http//www.citi.umich.edu/u/provos/papers/practical.pdf

Beyond all the math, the section titled Detection Framework basically states that *if* you know the algorithm/tool used to 'hide' data within an image, the best you can do is determine the _probability_ that an arbitrary carrier image has something hidden in it.

So, for example, if you take an image and hide something it with JPHide, and then use StegDetect to examine the file, you will get a probability the something is hidden in it. The same is true if you select an arbitrary carrier image…you simply get a probability, based on the algorithm.

Also note that Niels Provos has created statistical algorithms that are not as easy to detect.
