I know there are a number of places online where you can upload your digital images and they will send you high quality photo prints in the mail. From what I've heard, a lot of these places are higher quality and cheaper than what you find at the local machines where you can take a CD/memorycard/etc. Is this true? Do any of you use any of these services and if so, which ones do you use? Finally, I'm looking to at getting a poster printed off of a photomosaic that I made (it's a huge image). Anywhere that would be best to get this done? I would take it to a Kinkos, but I have a feeling that I could get it done a lot cheaper online. Thanks!
