Typically when I’m working with photos, I’m doing graphic design type work. I’ve been using GIMP for this. GIMP is meant for raster graphics editing.
You could also use Inkscape for vector graphics, or Krita for more digital painting type work. But I know all these tools are very powerful and overlap on some use cases.
Do you use any AI-type tools? I use a image upscaler called Upscayl. It works really well and works entirely locally.
Do you know of any tools that can remove backgrounds? This would help with help with the type of graphic design I do.
What other tools do you like to use as it pertains to images?
Well, it still is OSS and one can still compile from source code. Or you can buy your binary. Never heard of Libresprite but looks fine if you absolutely want FOSS.
