You could use an "inline image". The technique is described at for instance Base64 encoded images embedded in html (search for base64 image html for other resources).

Get the base64-encoded string of the image data bytes, using Convert.ToBase64String for instance, and then use <img src=data:image/gif;base64, and append the image data.

So you can bind it using something like this

<img src='<%# string.Format("data:image/gif;base64,{0}",
 Convert.ToBase64String((byte[])Eval("ImageDataBase64")))%>'/>

Of course, this is only recommended for small images. Also note that you should change "gif" to the actual format of your image.
