I'm not that familiar with all content negotiation and MIME type issues, but I have been wondering whether content negotiation allows for the automatic selection between color and monochrome variants of (inline) pictures. If it does not, it should. One of the biggest problems facing web picture designers today is to make their color pictures look good when dithered on a monochrome (black and white) screen. I don't believe there are separate mime types for monochrome and color variants of gif/jpeg/... pictures, so maybe HTTP needs to an additional accept header, Accept-Color, similar to Accept-Language. For example: Accept-Color: monochrome, multicolor;qco=0.5 Accept-Color: 8bit, 2bit;qco=0.5, 24bit;qco=0.7 Color types would include something like: monochrome multicolor greyscale 2bit (=monochrome) 8bit (8 bit multicolor) 24bit (24 bit multicolor) Maybe there should also be something like an `8bit, but I prefer it if you only use 100 separate colors' type, I don't know enough about the problems of adequately rendering multiple 256-color pictures, all using different colormaps, on a single 8-bit color screen to be the judge of that. Koen.
