Saving pictures with alt text names

I need to save many pictures with file name as they are in alt text for that page for example:
https://www.flaticon.com/packs/leaves

Any help with js? Tired to rename manually.

There might be an existing browser extension to do it.

I did try many picture downloaders, and seems like "image downloader" for chrome can name picts with that tag. Alas, it gives them wrong names.
