i don't know if you are still looking to enlarge images. the term is called upscaling. you can do it in photoshop but most semi-pro photographers tend to use fractals. the stock agencies want 50mb files as a minimum, the magazines sometimes demand 100mb. so a lot of pro photog's tend to take their pictures at around 10, 12 or 15mb and then use upscaling. if you still need more information please send me a private message.
