Im working with granite murals in the ball park of 5x7 feet which requires a large image to start with. Large Image means huge file size and im running into computer issues with those size of files, does anyone out there also work with extremely large files and if you do how do you allow for your computer to handle the file size??? I have 3+ gigs of memory and my computers are less than 2 years old and I just can't seem to find a computer to handle the projects im working with...Any advise???
