In my Android OS class recently the instructor showed us a feature of Eclipse that automatically formats an uploaded image into low, medium and high dpi images. He was running Eclipse on an Apple notebook, but when I looked at my version of Eclipse on a PC the option wasn’t there. 😦 I did find this website (Android Asset Studio) that does the same thing: http://android-ui-utils.googlecode.com/hg/asset-studio/dist/index.html
(The website didn’t work in IE, but worked fine in Chrome)
I am going to check into whether Eclipse for Windows has the image formatting option . . .
