The Mediathread Extension allows users to ‘import’ items from compatible websites. If an instructor has designated external websites as a source for analysis, those websites and the extension that interacts with them are found on the right side of the home page. “Add to My Collection” page. You can select items from the web that are not specifically listed as a source but not all sites are guaranteed to work as some sites have privacy settings that makes the items unable to be collected.
Follow instructions in the “Import into Collection” page to install the extension. The specific instructions that you see will vary depending on whether you are using Firefox, Chrome or Safari.
Once a you have installed the extension in your browser, you are ready to import images and videos into Mediathread from websites recommended by instructors.
Instructors designate recommended sites in the Instructor Dashboard by clicking "Manage Sources" and selecting from a list of websites that are compatible with the Mediathread bookmarklet. Sites not on this list might still interoperate with the bookmarklet -- and may be individually added by an instructor (the form for this is beneath the list of sites listed in Manage Sources").
Note that the extension doesn’t actually copy items into Mediathread. Instead, it references and embeds them. This allows Mediathread to work efficiently with a variety of media formats hosted in a variety of ways. Because of this, if you see a pink box instead of media, its likely that the media link from the external site is broken and the media will need to be brought into the collection again.
Troubleshooting: If the bookmarklet is not working for you please make sure you have disabled adblocking and privacy protecting plugins such as https://adblockplus.org/, https://www.eff.org/privacybadger or https://www.eff.org/https-everywhere from blocking mediathread. These plugins should be configured to trust mediathread.ccnmtl.columbia.edu.
