I would like to set a folder icon in Mac OS X 10.6.

I found an Apple KB that mentioned you use "get info", then double click the folders icon and paste in an image but that didn't work with a png file.

Any suggestions?

Will that work if the folder is also a stackable in the dock?

It should be made into a proper icon first, that's probably why it didn't work. I'd check out this tutorial on How To Create Icons for Mac OS X.

To change an item's icon to another one:

  1. Select the volume, application, folder, or file whose icon you want to stamp onto another, just click the icon to select it.
  2. From the File menu, choose Get Info or press Command-I to open the Info window.
  3. Click the icon in the upper-left corner of the Info window to select it.
  4. From the Edit menu, choose Copy or press Command-C.
  5. Select the volume, application, folder, or file whose icon you want to replace.
  6. From the File menu, choose Get Info or press Command-I.
  7. Click the icon in the upper-left corner.
  8. From the Edit menu, choose Paste or press Command-V to replace the icon.

what about if the folder is stack in the dock? – cbrulak Dec 22 '09 at 5:34
It depends on the folder's name as the stack sorts alphabetically I believe. The stack's icon is chosen by whichever application is sorted at the top of the stack. If you want a folder to sort near the top of a stack, start it's name with a 0 (zero). – John T Dec 22 '09 at 5:47
Folders in the dock will show custom icons after you log out, or you can drag the folder out of the dock and then drag it back in and it will update with your custom icon. – ridogi Dec 22 '09 at 23:48
You can also right-click on the item in the stack and choose Display As... > Folder instead of Stack. – jsejcksn Sep 4 '10 at 18:56

The above but use .gif files if you can I have found that these are better. .png files dont work for me and .jpg files seems to have a back ground.

Or: use Preview as the intermediate. First open an image file, or paste any format, into Preview. Next, copy from Preview. Finally, paste into the Get Info window. – Arjan Sep 4 '10 at 19:00
