These are crazy!
For the uninitiated, what are some of the best places where people share similar creations? Discord servers or Reddit or whatever
There are plenty of places, but I make my own so I don't explore. However, a very good place to start is unstable diffusion discord. Lots of good information, knowledgeable users, and channels with images to scan through. I'm sure you could ask others there for links to other images to peruse. Then there is the darkweb etc. Do a websearch for Automatic1111, Vladmandic, ComfyUI, Invoke AI,... there are many other WebUI and services to be found. Just be sure to use .safetensors and not .ckpt these days as ckpt extension models can contain virus or do things to your computer you won't like. Good luck out there. Oh, Civitai.com is the main place to get spicy models, and LoRA/LYCORIS to alter the look of the model in various ways. Google the terms so I don't have to explain. Huggingface is the main site for non-spicy models and information, but is no longer mandatory to get things rolling as there are 1-click methods these days to get Stable Diffusion running on your machine locally, and various tweaks to get it running on low VRAM GPU.
