OK, I'm finally got around to downloading a collage app like Pic stitch and am creating some collage pics to print, but curious - are the prints square or are the 4x6? Looks like all the collages end up being the same total size, so can anyone tell me what the final size is?
I use Diptic, with an add-on. You can switch between square and rectangles for the same layout design, using a sliding bar to size. You can also vary the width of white space, radius corners, etc. Works great with a Selphy.
