well, there are formats that have impressed me. The Mpg-4 format which requires plugins all over the place is really amazing, from e-vue. They also provide a plugin atleast for IE to browse the images.
I dont know if you can compress images outside the windows platform however. If your looking for supreme quality however, you would need to stay away from the lossy formats and probably go for TIFF which is a great format and is also supported by any major software. PNG however is abit "strange", woudnt sendt PNG images to a publisher... You could ZIP the TIF images on the HD to same space, you often get good results on this. This would also make the downloads better for the user, and since all the browsing online would use thumbnails you dont need to waste CPU do depack the images, since you all users can depack a ZIP file (thats the least you would expect from a user that purchase a High resolution image). Ive created such systems myself, and my sollution was another : Plug in a new harddrive. We save the images as jpg, tif, eps, ai or whatever the original image was created as, and create thumbnails at various resolutions in high compressed jpg for fast browsing. Often I tend to ZIP the lossless images aswell, but then again I dont need to since HD isnt a problem atleast in my case.
