What's the best icing/glaze to use on a cookie along with an edible image if you plan to package and mail the cookies?

..I am going to move this to the cookie section. Maybe someone will see your post there and be able to help you.

There's a recipe here that might work for you...

I have been using icing from a tub - Betty Crocker or Duncan Hines. Vanilla flavored. I just put a thin layer on the cookie then place the image on top. I then outline using Fondant icing writers from Wilton. The Fondant icing dries super nice. I just wish they came in more colors.
