While we can print really large photos, one of the things we face all the time is that you can’t ship things larger than 36×48″ without getting big charges from Fedex. The way around it is shown here: split the photo into 3 smaller panels for shipping.
We find this works quite well to get a really large photo up on the wall, and people find them to be striking. They don’t seem to mind that they are in three pieces, either.
This way, a really large 4×8′ photo breaks into three pieces 32×48″. Fedex and UPS will take them that way, and you get a terrific large format photo with very little fuss. The panels come to you ready to hang on the wall.
