Image Manipulation -- Graphics Question

I have imported a black and white *.bmp image into Mathematica and converted it into something the kernel can manipulate(the process was unusually complicated!) using the Convert to -> Input Form -> Standard Form and then removing all the NULL statements. However, I am unsure about the next step. I am interested in converting the 2-D image into a 3-D image by using the coloring of the image. That is, the darker the image, the higher the point should be plotted on the z-axis. For reference, I would allow black (RGB[1,1,1]) to denote a length of 1 along the z-axis and then plot all the other points accordingly. However, I have been unable to do this. In mathematical form, the image is now something like this: Show[Graphics[RasterArray[{RGB[0,1,1], RGB[0.09,1,0.02]}, {RGB[0.89,1,0.67], RGB....}] with a few other commands. I am not very familiar with the RasterArray command either and I would appreciate any help concerning this command and how to do what I want to do with my image. Thank you. Elvis Dieguez
