Here is an example of a 13 image collage that would cost 15fg if you provide the screenshots or 20fg if you do not:
I will gladly break up the images into 1-3 different collages for the same price, whatever makes the most sense for your posting needs.
So, if you needed 1x collage with 6 images and 1x collage with 7 images it would be the same price as 1x 13 image collage.
