So great, thanks a lot, does all the things i need :)

This Is Wonderful!!

Downloads only thumbnails, no way to rename files.

ZIPで保存したい人向け。画像そのまま保存は出来ない。保存先指定も出来ない。

I added this to download some SVGs. Unfortunately, it does not do SVGs. Last I checked, SVGs are images too. It's not very useful for me, but it looks nice. So that's good...

I click on a webp image, and this add-on doesn't find it?!?
