Have you ever wanted to create a wall-sized print of an image? It's not such a complicated feat using software like Photoshop, but it is not necessarily an easy task either. As I was searching for a solution to this problem, I stumbled upon Block Posters, a free online tool that promises to "create any size wall poster from any size image". A rather bold boast, but from my experience so far, I have been very impressed. An easy to use interface, enough options to create your poster the way you want, in all, a really great tool.
Go take a look for yourself, upload an image and print out a large poster; I'm sure you'll appreciate the ease of use immediately.
