I got started by following the sticky post in this community. Warning: there is a bit of a learning curve to get good, but everyone should at least try because its not hard to at least get going.

https://github.com/AUTOMATIC1111/stable-diffusion-webui is the go-to web ui and it's fairly easy to set up, not much harder than running a regular installer for any other software, just make sure you have the required python version installed.

You mainly use text prompts, but there are ways to use example photos to get similar images. You'll want to look into the controlnet extension, and specifically the "reference" modes.

Glad you like them!

Thank you!
