Heyy,
For a lyout I'm making I want to have an image in the shape of a key, I've been looking online and googling like crazy to find one! I want a download of a custom shape pack, I've found a couple that have keys in them, but it wouldn't work to put an image inside of it (the key is too narrow)

Anyone know of a good website that I could find what I'm looking for ?

Photoshop comes with the key shape already. Just press the little arrow in the Shape Preset box, then go to Load Brushes >> All. The key shape is there.
