That depends on the type of bmp file you are reading.... firstly, you need to retrieve the header info;

In the header info, you have things like the height and width of the image, the bit depth (eg 8, 16, 24 bit).

If the image is to be displayed before reading the pixel values, then you don't need to get the file header. This will also work for gif, jpeg, etc. The fastest way to do this is to use the GetPixel API call. A simple loop can iterate through the image.
