I need help in finding a software that can help me enlarge a photo and split it in sections so I can cover a wall. Is there a software I can use to help me do this? Thanks for your help.

Are you looking to cover the entire wall or are you trying to make a big photograph to frame and hang on the wall?

I want to enlarge a picture big enough and split it into sections so I can place onto a large space (split an enlarged picture into 9 8x10 frames). Any ideas?
