Hi, Stable diffusion is a free software and you can install easily. Just follow some instruction on the internet like : https://www.dexerto.com/tech/how-to-install-stable-diffusion-2124809/
After you can install some models from https://civitai.com/ . My little free software lets you remove the background from you image folder because Stable diffusion doesn’t produce images with transparent background. I called it “MR Stable Diffusion Background remover” because in the future version it will call also the api in stable diffusion. http://127.0.0.1:7860/docs I will clarify this on some notes to avoid people to think something different. Thanks for your comment, I hope you will be able to install it. Stable diffusion it’s a great software that can help a solo developer to do some nice games.
