I have 251 images that are 128x128 in size; I need to create one big image that includes them all tiled together.
The image will be 32128x32128 in size if all goes well (Paint.NET says it will be 3.8GB in size, fun times)
I need to do this systematically, with a tool or a script since I might have to do this a few times - it's very tiresome to do by hand. I have programming skills, so if the solution requires that, then no problem.
If your idea does not work for such a big image but would work with a part of the images, then I'd like to hear about it anyway.
