It's an image format issue rather than a database issue. You could try an image-related group for a more informed answer than mine ...

AFAIK, the problem with JPEG is the compression, which degrades the image. With GIF, the colour depth may be compromised to save in the GIF format. I believe TIFF is commonly used for "master" copies of images because it has a non-destructive compression algorithm, i.e. no degradation but much more efficient than a bitmap.
