Image Size Greater Than Margins?
I think I know the answer to my question, but I would like to make certain.
I downloaded the template for a hardcover (8.25 x 10.75) and the margins on the template page are Top: 0.6, Bottom: 0.61, Left and Right: 0.5. Those margins would fit an image with a width of 6.94 inches and a height of 9.54 inches (if my calculations are correct). Can an image exceed the margins a little (e.g., 7.25 in. x 10 in.) or must the image stay within the margins?
