From zFlick's website:
zFlick is a free Adobe® AIR™ application for viewing and saving photos from the Flickr service.It's a simple download from two established names.
On a side note, although I'm enjoying it on my PC, I couldn't load it on Maria's Apple.
If you decide to download it, please let us know what you think.

We are grateful to the developer of zFlick for making the necessary changes for everything to go smoothly. I just installed zFlick on Maria's Mac and she's been enjoying wandering through Flickr's Zentangle galleries.
Enjoy these two YouTubes from Kit Murdoch in Australia.
This one shows how she installed it.
This second one shows how she uses it and includes some helpful tips.
