In a 'PNG' image all the pixels that the program generated are still present, exactly as they were generated. In a 'GIF' image, however, pixels may have been altered in order to accommodate a smaller file size. I think you're thinking of JPEG. PNG and GIF both use lossless compression, however GIF only supports 8-bit colour and 1-bit transparency. For images with no more than 256 distinct colours, PNG and GIF will probably give identical results. -- Greg
