You can now create a piece of content on your Drupal site(s) to display a list of images from one or multiple Instagram accounts. You can set the number of images to show and the width at which the images will appear. Full documentation on this feature is available on the Library & ITS Wiki.
If you want to use Instagram on your WordPress sites, you can activate the Simple Instagram plugin, then configure the plugin (start with the “Registering and Activating” header on that page).
