// Photoshop Script to Create iPhone Icons from iTunesArtwork
//
// WARNING!!! In the rare case that there are name collisions, this script will
// overwrite (delete perminently) files in the same folder in which the selected
// iTunesArtwork file is located. Therefore, to be safe, before running the
// script, it's best to make sure the selected iTuensArtwork file is the only
// file in its containing folder.
