Feature request: "ils" thumbnails (icat but to list images)

[z3ch5]

Thanks for Kitty for being great, as the project describes itself featureful , there is a thing that I am really missing in terminals, which is "thumbnails".

icat is great for showing images, but it misses small scripting part to make images listed like lsix do, and as I read in #2511
Supporting Sixel could not happen in the near future, and I do agree that kitty does indeed great job in showing images, just if you may consider showing thumbnails it would make people not in the need of using a file/folder manager like ranger, and even with ranger, it would be a difficult to show tens of images and it's containts at once.

Expectation:

PS: I already have seen the project https://pypi.org/project/pixcat/
but it is an extra python library, plus it doesn't show thumbnails with the name of the images under it and to show them in one line under another like lsix do.

Sixels aren't required to draw mutliple images at once, Kitty can do so easily with its native protocol.

Someday, sure. In fact the original reason I wrote the graphics protocol
in kitty is to replace https://github.com/kovidgoyal/iv with a terminal
implementation. However, I have no immediate plans to do so.
