I first found this add-on while had been saving opened images from tabs in Chrome and trying to find a little easier ways to do it, as had a hard time finding anything specific for my use case in Chrome.
Well, the idea is great I admit, with a click you can save all opened images in tabs, and in that it works.
However, after using it for a while, the implementation leaves, well, some to be desired, at least in my use case.
In Chrome, if I open an image in a tab I can simply drag it into a folder. But having 60+ such tabs open can get a bit tedious so I wanted to find something more streamlined.
This, while it does the job, seems to require download of the images again, unlike Chrome which simply saves the opened image when dragged, meaning that part works even offline. That also means it puts more strain on the website where the images come from.
Also, if there's any special characters it messes the filenames, doesn't happen when dragging an image in Chrome.
So, while it seems to do the job, the way it is implemented just isn't for me.

This addon can save biggest image even from normal tab and then auto close it, PERFECT!

What an excellent add-on. It's really really good. I'd only like to suggest a feature that I think would be interesting: a way to download a picture automatically after a certain amount of time that is set, and each time a new page is loaded on a tab. (Essentially, I'd love this in order to 'mass' download FB albums by going picture by picture but without having to use a shortcut).

I can't thank the developer enough for this. Now my e621 browsing experience has been enhanced very massively!

Excelent complement! jus i have one suggest, it can give a range for image size for download.

I've used this addon for a couple of years now. I love how it allows you to download images from every tab at once; it also allows you to set custom rules based on the site you're visiting for how. and under what circumstances, the image should be saved which has been a tremendous time saver.

Very interesting and Promising Extension! It really downloads the Largest size of the images in the chosen Tab. BUT I gave only 3 stars because: For example in this web link: (https://xenofontos.com/portfolio-item/east-residence/) I tried to download the pictures from, (It has 22 photos), but the extension downloaded for me only (12 photos).
In the Preferences I have choose to download from the:
-> Active Tab
-> Image Filter: "All Images".

Fix this and I will change my rating to more Stars!!

Really saves time and effort when you need multiple inspirational images or looking to work offline. Excellent work.

This should be called "Image Download Canceller" because all it does when I click on it is bring up a notice "user cancelled downloads".

Awesome. Just what I've been looking for. Would appreciate if it detected Twitter's various urls it uses for images but still super happy.

EDIT:
I am going to revise this from 2 stars to 5 because from what I can see the issue I am having is with Archive.org and not the add-on itself. I have determined the images that weren't downloading were ones that were not true direct links to images, rather they were in some sort of frame added by Archive.org that was preventing the add-on from finding the images. This frame seems to be used at random by Archive.org. On some websites they use it, on others, they don't. A true direct link to an image on Archive.org can be revealed by the URL; it will show "im_" after the date/timestamp in the address. Whenever it shows "Im_" the images download fine and there is no HTML source to look at, it is a direct link.

When there is no "im_" in the archived image URL, it looks like a direct link to an image but it is not. The page source can be viewed as it is considered a webpage not an image.

So yeah, this is not the add-on's fault but a flaw with Archive.org. As far as I can tell this add-on works 100% to download images conveniently.

ORIGINAL REVIEW:
At first it was working good but have not had much success lately. For some reason, it doesn't work on certain archived websites on Archive.org. It singles out entire archived domains, I don't know why. There doesn't seem to be a discernible difference between two different archived websites but on one website image-only tabs will download fine, 100%, but on another, 0 images will download, 0%. This is not a case of maybe the images didn't archive. No, the images are opened up successfully in the tabs. It appears to be singling out particular domains, probably not intentionally, but some sort of glitch I guess. Simply put, it works on some archived domains and not on others, and it seems to only be affecting the direct links to images (image-only tabs), so for example, the thumbnails on those affected domains still work. Odd! Very odd!

might be much better with option to choose which image(s) to download.

firefox 56 之后集图工具不能用了，我需要的就是不同标签页批量存图的功能，大部分扩展都没有，总算找到一个类似的扩展了！

This add-on is fantastic! Does exactly what it says in a simple way. Very easy to use and great easy settings to customize the output. The best of its kind. Thanks for this
