hey i have looked into
Block Posters - Create large wall posters from any image for free! and it looks like this is a pretty cool system. For some of the folks that may know alot more about this than me, could you please try this and let me know about what settings that is needed to get a clear picture. this is totally free and only takes about a minute or less to do the whole process. I uploaded a picture that i had on my computer that was taken from a car show (very clear picture) but when you view what is going to be printed, it is very blotchy. Any help would be greatly appreciated
Thanks
