I need to compare two bitmap images in vba and also obtain a third image which is a difference image formed by the difference of the RGB values of the pixels of first two images. Please let me know how this can be implemented in vba

If it's an uncompressed bitmap file, you can just do a byte by byte comparison. If it's compressed or uses any other specification, you will have to read the spec file for that format. Or find a library that contains image editing functionality.
