This is my RainbowImage demo from my Code Rage 2007 presentation.
Demonstrates using HTTP range requests to download parts of multiple files and joins them together.
Uses Indy 10, but could easily be adapted to Indy 9.
Normally you would want to download parts of the same file, but for this demo is uses different color versions of the same image.
The images may be removed later if they become too much of a bandwidth drain. If they do then an updated demo will be provided which uses alternative image sources.
The images it downloads are colorized bitmaps of the wallpaper created by Zoltan Komaromy. The original wallpaper can be downloaded from MandalaPainter.com. Thanks to Pawel Glowacki for the link.
