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.

It's great but path rules are buggy -- sometimes work sometimes not ("Path rules failed" error)
Hot key also never works for me.

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

Great addon. Very efficient and easy to use. With a little tweaking of preferences it's everything I was looking for.

This is what I find.

Used to have one like this that at first was a lot better, But since Firefox Quantum I could only use this one and it has gotten so much better.

This Addon filled a much needed void. I'm really glad this developer picked this up. They have made this so much better than any other previous and current image saver.

100% recommend this addon to batch save images.

[to the developer] Thanks so much for putting so much work into this project. Your hard work has really shown through with the progress of this addon and it's in such a good spot now. And another thanks for being so responsive to people in the reviews. Again, I'm really glad it was you who made this addon.

After looking at the preferences, this worked an absolute treat, don't even need to have the image opened in its own tab.

Good extension, although it lacks vital options, such as an easier to get to Settings page (The settings page is really clunky right now), and the option to set the maximum width & height of the images.

where can i find this add-on for opera or chrome?
please, add a hot keys in latest firefox versions

Edited: Like I said below, the bug was fixed in version 2.1.1, so 5 stars!!

This add-on is awesome, but as of 2.1.0 version, the program has stopped working as intended. I had to downgrade to 2.0.5 for it to work as before. Please fix it and I'll give it 5 stars! :)

Been using this addon for a while now and 've loved it. However, ever since the update it doesn't work anymore. I can't see the icon on the Toolbar so I can't use it. Clicking on "Options" inside about:addons doesn't do anything. I've tried re-downloading but nothing works.

Works Perfectly.

Only thing missing is the ability to save somewhere which isn't in the download directory.

best app for multiple image saver.. great app thanks you doveloper

Would be great thing but doesn't work for me at all. After I press the button I see saved file in destination folder but the file is corrupted and its size is always only 24B. File name is correct.

The problem is photos are with URL like http://www.domain.com/picture.jpg?token=123 and seems like extension doesn't use the token parameter so then the result is not the JPEG image but error message "Invalid token" what script returns.

Saves me a whole lot of time.

Great, but would be nice if there was an ability to save the images somewhere besides the downloads folder (especially to a different drive)

This can be worked around by creating a symbolic link somewhere in your downloads folder. Running command prompt as administrator: `mklink /J C:\Users\Me\Downloads\MyCoolLink D:\Where\I\Actually\Want\The\Images`

I cant believe I found something so similar to the previous image tab saver I had. It has a simple function and it does what I want it to. And it seems this one comes with additional functionality.

A thousand blessings on you and this wonderful add-on. Keep up the fantastic work on this project!
