I bought a print from the internet which is 11 x 17 but the image has white edges around it which when I hang it up I don't want to see but just the full picture, will buying a frame that is matted hide the white edge bits, they are about one inch all the way around?

I don't want to cut it because I'm paranoid about taking any of the picture off so will a mat job hide it?

It's like a white border... the image description is "Posters printed on 11 x 17 inch paper with image size of approximately 11 inches x 15 inches (28 x 38 cm)." the print has came and there is white around the image.

HELP???

I'm probably worrying over nothing but its the first time for me buying a frame etc.
