I made a smol extension for image filter effects

[Zuellni]

It applies discount photoshop filters to the image in pixel space just before it's saved, also works in extra tab. Stuff like auto contrast, pillow filters and some instagram-like ones. Not sure it's worth adding to the index but just in case anybody wants to give it a spin: https://github.com/Zuellni/stable-diffusion-webui-image-filters
