Almost all images are created using online generators, so there is no special workflow. I've uploaded jpegs with only the generation parameters because my upload bandwidth is poor and PNG would have taken too long. If for some reason you want the original PNG, leave a comment in the image, and I'll upload it for you (limited to 3 per customer! 😅). I also have a secondary "overflow" account when I have too many images.
