Folks, I am going to enter a pic in the Sydney International Boat Show. On the entry form guidelines it states that the finished photo must be 10x15 inches (254x381mm)

In Gimp it tells me my image size 4128x2328 pixels, 57.3x32.3 inches and 1456.27x821.27 mm.

Are they saying that I need to scale the image to 254x381mm. The images are entered online so if they are printing them would they not print to the overall dimensions.

Any thoughts?
