RE: Where do you get your large digital photos developed?
The process ofoto uses is essentially the same chemical process that would be used for traditional film pictures. The method of getting the picture onto the paper is different, but the processing is the same. I would not worry in the slightest about the permanence of those. What you absolutely *don't* want to do is use one of the kiosks which are thermal printers. They may have improved since I tried them a decade ago, but the thermal prints I made have faded and turned odd colors over the years. Luckily they weren't anything important!
I've gotten beautiful 8x10s from ofoto. I've never printed anything larger than that simply because I've never needed to. But I do have friends who use ofoto all the time and have printed larger format pictures with no problems at all. (Ahem. I should probably mention that those friends are former coworkers and that in my former life I used to work for Kodak at this point... ;) )
Honestly, if you're happy with your smaller prints from ofoto, I would just order the larger ones from there. You could always try just one and see if you're happy with it.
