Image Downloader for IW is a lite addon that lets you easily download desired images from the Instagram website.
Simply add the add-on to your browser and open the Instagram page. Once the add-on is active (toolbar icon is dark grey) you will see a download icon next to any image (on the top left corner side). Please click on the icon to download the image to your machine. Please note that the download location is the default location for download in your browser. This add-on will capture and download the highest resolution image to your machine.
