Well, for starters, you can have pretty cool backdrop pics, but as mentioned, you will need to use a graphics program to reduce the colors, and possibly dither the image to make it look OK. PPaint is good, (v. 7.1 was given away on an Amiga Format cover disk) I use ImageFX. NewIcons V. 4 is a must for pre-OS 3.5 systems. You might want to consider Copper-Demon, a prog. for doing smoothly fading colored backdrops, but even better, the affected pen can be changed, so you can have say, active windows display in a smooth multi-color fade, instead of just one color....Oh, Jeez, I can't explain it, just DL from Aminet!!
Other Ideas: Birdie, lets you use pictures/patterns for active/inactive windows, nice idea....but not too stable on my A1200T. Using programs like Iconian to make your own custom icons. (I have an icon for my Seagate 2.1GB SCSI drive which was DL'd from Seagate's website....'cover off' photo of a SCSI HD, which was shrunk, color-reduced, cleaned up in ImageFX, then loaded into WB3.9's IconEdit to add the glow. Looks nice!)
There are probably more ideas that I am too tired (or drunk) to tell you now. Good Luck!!!
