A few of the accelerator programs do their tricks by dropping the pictures to 256 (or less) colors and compressing them up on their proxy server.
Sometimes it gives itself away if a right-click shows a "Show full image" or other message.

Windows XP . Broadband Connection - when on-line all
the web pages I visit are poor quality graphics and limited colours. I have a graphics card fitted with
correct drivers etc. I have checked my internet settings and all seems well. My Icons etc pictures are all fine and detailed. Any help appreciated.
