I'm working on a site where the primary audience will be visually disabled/blind, but it needs to be visually appealing at the same time (for the smaller percentage of sighted people who are family, friends, volunteers, etc.). Thanks to the beauty of (goddammit MSIE) almost-cross-browser-compatible CSS, most of the site is accessible and more-visually-appealing-than-plaintext, but I'd like to use some image replacement technique that works with msie5+ on windows, firefox 1.x and up, and safari, bonus points if it's accessible (truly text-only when the user wants it, screenreader-friendly, you get the idea.). If it works in east-asian languages (particularly korean), that would rock. There seems to be a LOT of different methods floating around, and I'd like to know if you've used any one of them somewhere I've looked around at a few (like sIFR, phark, gilder/levin), but they all have their (ever so slight) issues. In fact, if it seems very unlikely to work the way I want, anything server/client-side or whatever will work, but the host limits me to php, perl, and asp (not .net). Pretty much any pointer will be much appreciated.
