I really really wants to default my desktop pix to the right side of the screen, so I have trigger pix beside SeaMonkey's composer, but Ubuntu doesn't do it.. it defaults pix centered...
I did enjoy "Irfanview", how it handles pix in Windows... Irfanview was the only good thing about a Windows OS... "Subdesktop" was nice till I found it's got bugs, that probably send files, like it's a pix trojan-collection program... "Gimp" didn't work well in Windows.. Maybe it does now..?
"WinWall" sets pix to default to either side of the screen, but it doesn't work in Linux... I tried WinWall in an Ubuntu-

800 with Wine.. It seriously damaged the Linux OS similar to what Storm does to a Windows OS... It's quite the experience... Next time you must format out a Linux OS, before you do, install Wine and WinWall, then reboot... It's worth the experience...
