>I would like to comment on the current discussion about Image Storage and
>Image Distribution. A 35mm slide is still the highest possible resolution
>commonly available. The original 35mm slide image is important both for its
>resolution, and for the purposes of copyright and credit. Low resolution
>images distributed in JPEG format (my current preference as smallest file
>size with the best image quality) may be easily sent over slow speed
>network connections or the Internet.
>I would advocate a system with the original media is scanned at the highest
>possible resolution and stored locally, on CD-ROM for example.
>A low resolution image (JPEG) should then be distributed to participating
>gopher servers and/or FTP sites, along with adequate information to get to
>the source of the images.
>A low resolution image is all that is needed initially for viewing on
>screen. Selected high resolution images could then be obtained. This would
>use a much lower bandwith and reduce the strain on network resources.
>A group of key images could, perhaps; be distributed by CD-ROM to mutiple
>server sited world-wide, bypassing slow network links and providing local,
>or near local access to images, and image sources.
