If you need support from Yola please contact us via firstname.lastname@example.org or make use of our live chat service! We are working on a new approach to community-based support and during this transition period we are not adding any new threads to this forum. Many thanks to everyone who has participated over the years and we look forward to unveiling a new peer-to-peer support system soon!
As per the Yahoo! terms of service (http://info.yahoo.com/legal/us/yahoo/..., Flickr hold the license to use, distribute, reproduce, modify, adapt, publicly perform and display content for the purposes of providing and promoting the Yahoo! Group. This implies that the Flickr widget, owned by Yahoo! who also controls copyright of the material, allows you to display Flickr images in this manner.
My advice would be, assuming that you're not using these images for commercial use, to extend a basic courtesy by crediting the author(s) and providing a link back to their website or profile.
