There are many tutorials on the internet showing how to use Photoshop to up sample a small image for Poster Size Printing.
There are also stand alone applications and Plugin software to automate the process.

Subject: Software to enhance quality of Low Resolution Pics for Large Format
Hi Recently a customer brought in a 300dpi pic that was about 2.125" x 1.5" and not real good quality they wanted the poster 18" x 24". When we blew the pic up to that size it was very pixilated. We told them it would not look good. They took the job to a FastSigns shop and had them done and they turned out real nice. Is anyone aware of software that might enhance art for enlarging or is there a trick we are unaware of? Thanks for your help.. cp
