I am sure this will be of value to many. I found this image on Flickr by using http://compfight.com/ by switching the creative commons option to 'only' in the top bar, to only get images that are available to use under this licence. Then I searched for the tag 'celebration'.
I then put the URL for the image I selected (http://www.flickr.com/photos/40645538@N00/211157489/) into http://www.imagecodr.org/ This gave me some code to embed that not only correctly references the image but also puts the relevant cc licence icon(s).
I switched to plain text editor and pasted in the code to get the image and reference link above.
Thanks to Martin Weller for this helpful advice.
For anyone unsure about the different category of Creative Commons Licences and what they stand for, I found this page on Flickr a good summary: http://www.flickr.com/creativecommons
