I'm pretty sure I'm in the right forum here... I currently have a .PNG icon, and I would like to assign it to a folder, so the folder icon would be this one (It's a snow flake, which at first glance, makes me think of Winter Quarter for school, aka, the folder name.) I know how to assign the icon to the folder, without any problems. (Right Click-->Get Info-->And drag the icon to the Top Left). However, when the icon (which is transparent, I'm 120% sure) is displayed, the background is white. Normally this wouldn't be an issue, except the icon also appears on my Finder sidebar, since it's a folder I use a lot. Using Icon Composer (/Developer/Applications/Utilities), I tried making it an icns, just to see what would happen. But, like most icons I've tried, this appears when I drag it. And I assure you, this is not the icon I'm trying to make the folder appear as: So, my question is, how do I transform this transparent PNG icon to be transparent when it's assigned as an icon for a folder. Incase it matters, the icon is 256x256, with a 72 pixels/inch Resolution. I've tried playing with the sizes a lot, and I believe I read somewhere that the resolution actually matters for OSX to take the icon. Thanks for the help!
