If I'm not mistaken, the new Game Editor will be able to manipulate images, but know this: UpScaling or down scalling different image sizes may cause lag on older machines :O
great to hear. I found the CVS updates/commits page for Game Editor, now I can leep up to date with the new changes. But I have to say the MacOSX version is very responsive and the port has gone well so far(thanks to Andreas & Maks).
Cant wait for full screen zoom in and out(for iPhone especially)
