Where do I put Training Images that you can download in the post?, I'm new to all this and I still need to learn where everything goes, but I noticed that you can download these compressed files and I don't know if I should place it somewhere on my SD, I'm having problems because some lora cannot reproduce the character that said lora does
The training images aren't necessary for using the LoRA. They're only provided so someone else could use them to make another LoRA.
Are you sure you're using the LoRA correctly? Here's some info, I hope it's helpful. https://github.com/civitai/civitai/wiki/How-to-use-models#lora
