I am making a Harley Davidson cake and also a Hannah Montana cake and am needing an edible image for both. I do not have a edible image printer so can anyone help me out on how to get these?

Call some local cake shops. They may print one off for you.
I use one 10 minutes away and they charge $6.99 for all print offs.

I take the images I need to my local grocer. Their bakery does edible images, and they are more than happy to do mine as well. They charge me $5.00 a sheet, regardless of the number of images on it.

Aren't Harley Davidson and Hannah Montana copyrighted? Are we allowed to have those images done as edible images and then sold? I'm relatively new so I'm trying to make sure I know the rules but I thought those were off limits as far as selling them on cakes, let alone the groceries being able to print them for someone.
