are there any software out there that can automatically fit 2,4,6,8.... pictures into one single 4R,5R,etc.?

mas mura kasi magpa-print ng 1 5R kesa 2 3Rs. meron kayang software na gumagawa nito? right now, manual kong ginagawa using corel photo-paint (hindi ako marunong ng photoshop). sometimes i fit 4 pics into one single 5R size.
