Hi
 The distinction between a distribution tool and an archival tool.
For images, the best archival format that I know of is the tiff.
Not so much that there are copious tools for it but because
it is about as simple a formatting for images as one can get.
 When down loading I prefer pdf's. It doesn't mean that I think that
an archive should use pdf's to store the images.
