How easy would it be to take an image found on a website and turn it into a silhouette, print it out onto rice paper or an icing sheet to use as a cupcake topper ?

I have used this company with great success

I did some Shakespeare cakes which you should find at this link

They're cheap, they're quick and they looked good. Tasted alright too. They use edible ink so you're all good.

Thanks for that - I've put it in my bookmarks.
I want Karate images, but the only good ones I have found as silhouettes have got watermarks on them, and they can't be used.
By 'Karate' I mean, "proper" Karate pictures, not cartoony types, if you know what I mean
I have trained in Karate since 1980, so I know what I'm looking for !
