New to image generation - how do I use img2img models to alter existing pictures with good character adherence?

Basically, I can get decent images out of text2image models, but I want to be able to take those images and use them to generate different pictures with the same characters. However, whenever I try img2img generations (with an input image and a prompt), the people in the new image only vaguely resemble the originals. I'm using stable-diffusion.cpp with z-image-turbo, but am open to trying other models if those are better suited. submitted by /u/Janonymousse [link] [comments]
