I'm designing a site that wants to use lots of images, but while some users will be on broadband, other user groups will be on dial up or similar.
Is there some trick/module that can serve lower quality images based on a cookie, for example?
I guess I'm thinking perhaps a parallel set of image styles that uses a lower quality (these could be provided by image style quality module) and something that detects when one style is requested and switches it for the lower quality version?
Long shot asking for a technical solution to a design-based problem, but thought I'd ask in case anyone else has come upon this problem.
