Basically I want to arrange ~10 (11 is probably impossible due to non-printable area) images of sizes say 813 x 1185px (png format) on a canvas, which ultimately is being printed on A4 paper (so that I can cut the images out later). I already thought of a possible arrangement like this.
The actual problem is that I want to easily exchange any of the images for different images of the exact same size.
How can I do this or what software for Windows does that?
Motivation: These are "trading cards".
