Include a Flickr album as an image gallery
If you're using a Flickr account for images and have created an image album (or set), you can display those images by adding the Image Gallery - Flickr content type to your page, and entering the ID for the album.
You'll find the album ID in the URL when viewing the album in Flickr. Here's an example for the album displayed as a gallery below.
The caption in the gallery will be derived from the image title (and caption, if available).
A Flickr set can also be displayed as a Thumbnail Gallery, with a single image and caption accompanied by a navigation menu of thumbnail images. Just check the "Thumbnail Gallery" box in the Flickr Gallery content type to select this display option.
