The only thing it actually does is set default size in some but not all print layout programs. Changing ppi from 300 to 72, or the reverse, does *nothing*. What matters is the number of pixels, and the quality of the pixels. So if you're worried, make the image as small as you you're willing to have people look at it, and use as high a jpeg level as you're willing to have people see it in. On the other hand, most people who think web-resolution versions of their images have any commercial value are delusional, too. -- David Dyer-Bennet, dd-b@xxxxxxxx; http://dd-b.net/ Snapshots: http://dd-b.net/dd-b/SnapshotAlbum/data/ Photos: http://dd-b.net/photography/gallery/ Dragaera: http://dragaera.info
