Seconding this, their XnView MP version works on various platforms, too: https://www.xnview.com/en/xnviewmp/

I especially like the batch operations, for when I want to do stuff with format conversions, resizing, EXIF data and other things. Really pleasant software.

I used IrfanView before then, it was honestly great for Windows. It was mentioned in the parent comment, here's their page, too: https://www.irfanview.com/

But my use cases have been regular image operations, never really the fancy AI stuff, no idea what the software landscape there is like (have to mention, given the topic).
