This is a simple Google Gadget that I have developed for a website for a none-profit organization, the [Ann-Hua Rainbow Project] (http://rainbow.annhua.org/). It was first written a few years ago.
An example of this gadget may be find on this AHRP page.
This gadget is hosted on a Google Sites file cabinet, so it may be used with this URL if you don't want to host your own copy:
https://sites.google.com/site/ahrp1998/flickr-show/flickr-show.xml
However, not sure is Google's policy regarding hosting these gadgets out of Google Sites, so that may have to change in the future.
To use this gadget, a Flickr API Key is needed which may be obtained from Flickr for free.
