I saw a vendor at Oshkosk last year that turned pictures into posters.
Also, my flying buddy is also a "sign" guy and has just invested in a new printer that prints pictures for signs , instead of cutting vinyl letters for banners or sign material. He tells me and has show me samples of the printer printing out fabulous looking pictures, plus he has a laminator to make it last longer too..
This is new to him, just in the last two weeks, so he isn't up to speed 100% yet but I'm already thinking of things to do to our RV's....
The machine prints on material that is ...I think 54 inches wide.
So you could check with local sign shops to see if they have this type printers.
Hope it helps.
