Lossless formats are not suitable for web display of images. They're far too bandwidth intensive, unless both server and client are connected via a truly high-bandwidth connection.
There is an easy fix for your problem. Use a file format designed for this sort of use. PNG is NOT designed for the display of photographic images (It's designed as a replacement for GIF, not JPEG). You might be able to get away with it if you had a colo'd server (at least for users like myself on high-bandwidth connection) but as it is your site is an exercise in how not to present your images online. -Adam On 12/20/07, Polyhead <[EMAIL PROTECTED]> wrote: > On Wed, 19 Dec 2007 17:07:46 -0500 > "Adam Maas" <[EMAIL PROTECTED]> wrote: > > > On 12/19/07, Polyhead <[EMAIL PROTECTED]> wrote: > > > On Tue, 18 Dec 2007 22:11:13 -0800 > > > "John Celio" <[EMAIL PROTECTED]> wrote: > > > > > > > >> >I also refuse to use jpeg, png or nothing. > > > > >> > > > > >> Wow.
