We are a small print shop with both Fiery driven digital printers, and large format HP photo printers. We do a lot of jobs where we have to arrange many small photos to fill a 24" or 42" wide roll, and so far have always done it by hand, which is very tedious and time consuming. I'm wondering if there is a program where I can just pick a folder full of photos and have them automatically arranged to best fill the space, saving me a lot of time and paper. I'm sure there is one, I just don't know how to find it. It would also be nice to have it work with letter-sized paper and save it as a multi-page pdf in case we want to run it on our digital printers.
