As a web master i often use DPaint to make simple animations (i turn them into animGIF's or import into flash). It's been awhile but i've also used ImageFX to do things like lightning effects. Last year i used Distant Suns 4 to make some realistic sky backgrounds showing constellations, moon phases etc...
Use an A1200HD with 060 and 32MB RAM. To transfer files to my PC i use a modem to FTP the files to my web server then i FTP from server down to PC.
Have planned on backing up the A1200 and using WinUAE on the PC instead, to free up some space, but have never gotten around to it.
