Using a CMS such as Drupal you have an image processor that optimize images serverside. You can let your end users upload any picture direct from cameras or other sources. Adding captions, owner, rights, cropping etc. Images that are not made for web. The image are then optimized for web during the publishing procedure and the image are copied/cashed to several formats that the server program choose from when the image are displayed.
