so the algorithm.
1. You have selected a photo. I advise you to cut it to the minimum size immediately. It is important to precisely trim the bottom edge of the shoe so that the figure does not hang in the air later. I'll show you everything using the example of Daenerys Targaryen.
then in Photoshop (I use the free simple version of Photoshop online) you need to carefully clean the background with an eraser. You can not use the "magic wand" tool, it is a very rude and sloppy tool. just an eraser. The eraser should be with the maximum stiffness setting. Carefully remove all the crumbs and dashes along the edge of the background, they will then hang like gray flies on the render.
when everything is ready, you need to export the photo in PNG format. During this operation, you will have information about the size of the field in pixels. Put these numbers in the name right away, they are very important.
