Re: Problem with the quality of pictures on flash drive.
As joe said, if your saving them instead of copying them and if they are saved as jpgs or gifs, that could be the problem. These are considered a "lossy" format and each time an image is saved, compression is applied. Compression is often achieved by sacrificing the quality of the image. Instead of jpg or gif, consider saving your pictures as raw, bmp or png which are "lossless" formats.
