Anyone have any experience with online printing vendors that have pano capability? I've checked MPix and can't find the option, and Shutterfly has some choices but appears to be more geared toward canvas prints for home decoration, which I'm not really interested in. I'm just looking for a shop that'll do prints on glossy photo paper... I'll handle the matting and framing elsewhere. In the same vein, what is a standard pano size? I've got a few of different dimensions because I just arbitrarily cropped. If there's a standard so prints come out nice, I'd love to know. Thanks in advance.
