Since a photo is also protected by copyright laws, it is necessary to mention its source, unless it is a copyright-free photo. Here's what your footnote or endnote should mention:
Photographer or agency's name, "title of the article between quote marks (if the photo was part of an article)", in newspaper's name in italic letters, city where the journal was published, publisher's name, date (month, day, year), page number.
Also, don't forget to include this reference in your bibliography section as well.
