Citing Images

In order to cite images online - use the TASL approach. Include the:

T - Title :: the work’s title or name (if applicable), if such a thing exists. If the work is being published on the Internet, it is best practice to link the name or title directly to the original work.

A - Author(s) :: the author’s name, screen name, or user ID, etc. If the work is being published on the Internet, it is best practice to link that name to the person’s profile page, if such a page exists.

S - Source (link where you found the image) :: the specific type of license the work is available under. Linking to the license will allow others to find the license terms. Also, remember to link the works URL where the work is hosted.

L - License type (the Creative Commons license information) :: Mention if the work is a derivative work or adaptation, in addition to the above, one needs to identify that their work is a derivative work i.e., “This is a Finnish translation of [original work] by Allan Bell.” or “Screenplay based on [original work] by Allan Bell.”
