I just had a store which the customer wanted arm logos. The products didn't have arm images on the backend. The products were already in the store. It would have been tedious to add arm images to all the products and re-import them into the store not to mention the pricing would have to be re-entered etc. I made a new image that contained the arn image and the front image and simply used that art.
It would have been nice to just import the second logo and place it where I needed it. The font image is good enough to show an arm image to. I saved 30 minutes doing it this way but being able to add a second image would have been much easier especially since its easier to line up the second image if its separate.
