I got a travel coffee mug that lets you unscrew the bottom of the mug and insert your own picture to personalize it. There are pre-made graphics on the company's web site
, but I would like to make my own pics from a template. The problem is the shape, since it has to wrap around a conical mug, is of a weird shape. Is there any way to have a graphic editing program assist with contorting a graphic to the shape required?
