Perfect for downloading bookmarked images that I saved from my phone.

Since there is no description I'll explain for the people that don't immediately see the photos.
- Wait... Yes, you impatient potato.

If on the top right it says "Click to disable Insta download" then all you have to do is wait a few seconds and then all the images will appear. If it says "...enable" then click that and then wait a few seconds.
If that doesn't work then something (probably another add-on, script blocker, or something) is probably blocking the plugin.

What I like about this plugin the most is that I can easily drag the images onto my desktop and still preserve the size of the image.
