I bought some of these images with sky lander for my sons birthday in January, now I made cupcakes to put them on, I iced the cupcakes , cream cheese frosting then put the images on, it was the night before, late, next day get to Party take out of cupcake caddy, and all images had run, and. Couldn't even tell what the image was, now someone tell me what went wrong, I cut them out an put them straight on cakes,on top of frosting swirl, or maybe it was because they were in the fridge all night ?should I have made a base first out of fondant??? Thanks I have some handbag ones and don't want the same mistake.

thanks
