SPC1608 - BC Online:

This is a 3.5 min. video on how to find, use, and give credit to free, openly licensed images for your presentation.

From BCOnlineLibrary

Go to any of the links below to search and find free images to use in your presentations.

If you use an image with a Creative Commons license, you must give it an attribution. 

This is an ideal attribution

Because:

Title? "Creative Commons 10th Birthday Celebration San Francisco"

Author? "tvol" - linked to his profile page

Source? "Creative Commons 10th Birthday Celebration San Francisco" - linked to original Flickr page

License? "CC BY 2.0" - linked to license deed

This is a pretty good attribution

Because:

Title? Title is not noted (it should be) but at least the source is linked.Author? "tvol"Source? "Photo" - linked to original Flickr pageLicense? "CC BY" - linked to license deed

All other images used should follow the citation style required by your specific instructor (typically MLA for speech courses).

If the work is cited on the web only, then provide the name of the artist, the title of the work, the medium of the work, and then follow the citation format for a website. If the work is posted via a username, use that username for the author.

Artist or username. "Title." Medium. Website in Italics. Publisher of website or n.d. if no publisher name, date of publication or n.d. if no publisher date is given. Web. Date retrieved.
