Well first idea I had when I read this-- take pictures of your band mates and/or clients, won't they be impressed when the see their smiling mug beside their vocal track.
And yes take a picture of each and every guitar, bass, dobro and jaw harp in your collection.
If you're to lazy to take your own pictures of instruments just use google images and enter the name and colour of your guitar. You can then open it in Microsoft Office picture Manager or any editor and resize to 96x96 and then "save as" bitmap.
