Creating a custom Finder icon
Man what a runaround. You know that you can change a file or folder’s icon in the Finder by copy-and-pasting the icon from another file or folder’s Info window (using the Edit menu’s copy and paste commands).
But what if you want to build an icon from an existing png file?
You need two free tools: the Icon Composer from Apple’s Developer Tools, and a 3rd-party app called IconDroplet, available as a zip file from VersionTracker.
1) Drag the png image onto the Thumbnail target of the Icon Composer window
2) Drag the Thumbnail onto the other 3 image targets, extracting the mask as you go
3) Save the .icns file
4) Drop the .icns file onto the IconDroplet app
Congratulations, you now have an OSX icon resource that you can Info-Copy-Info-Paste to your heart’s content.
