Here is a service which takes a digital photo and allows you to create a poster along with some text of your choosing. Getting photos blown up to large size is nothing new, but it's a nice addition to have the option of adding text. So, a poster saying "Go Tigers!" or "Student of the Month" can be easily and professionally produced. This could also be used by students for science projects and similar projects which require the combination of images and text. There is no reason the image could not be a graph or other non-pictorial image.
