The following image formats are recommended - gif, jpg or png. Other formats may work, but there may be printing or display issues.
The image should only appear once per foil.

specifies a rectangular area that is correct, specified as (x1,y1)-(x2,y2),
where x1, x2, y1, and y2 are number corresponding to the x and y coordinates
of two corners that define a rectangle which specifies where the right
answer for this foil is located on the image. For example, (0,0)-(100,200)

situated in the upper left of the image, is correct. At least one
rectangle is required; multiple rectangles may be specified.
