Actually I think there is a way to do this, but you may not be satisfied with the results. As Crescent indicated you can load the picture as a 2d picture object on, say a flat plane and then use the camera to take another picture of it. Brief example and you can experiment with it a little to get the effect you desire. Move the camera as close to the object as you like, be careful of pixelization though, Make sure the material fills the viewscreen from whatever view you select. Render the image with normal anti-aliasing. When it's done rendering save the render to disk. Now create the an object you want the texture placed on. Open the Materials lab and go to the Picture Editor after clicking "P" on one of the channels. In the Picture Editor, load the render you just saved and keep it's alpha channel solid black. This will give you bump mapping with the bitmap image. Explore from here, and hope it helps. Kind of a weird workaround but it might do the trick. Sorry shameless plug here, I learned this one from BRYCE 3D handbook by Shamms Mortier. Nuke.
