It is an amazing tool.
Since the 5.10.0 update there is an annoying notification dot every time a page is loaded, even though there are no pictures. This forced me to downgrade back to the old version as it was too distracting. Until this bug is fixed, I am forced to reduce the rating, which is a shame for such a great tool.

ダウンロードした画像ファイルに、拡張子が付かない不具合がある。
There is a problem that the downloaded image file does not have an extension.

It's good, it downloads orginal size image, but it's download image with random name & without extension (.webp, .jpg, etc), to mark certain images & then bulk download all marked images is to hold Ctrl key & click 1st image then click all desired images without holding Ctrl key all the time, it needs to download image web page title name & with extension.

Does not work on Instagram

Should support zipping all images instead of showing multiple download dialogs at once. Other than that works great and I like how it sorts images from bigger to smaller.

The add-on works, but I used it with Pinterest and it detected way more images than there actually were. I mean, there were like 200 images, but it detected more than 800. Like what?? where did so many come from?? Also it doesn't have too many filters so I couldn't filter all those images.

you should add "download from all open tabs" on this extension.

Well-executed interface, but it seems to be unable to determine the file format (extension) of image files. Example: https://is.gd/81kDVV
