What's the best way to cite a photo from wikimedia?

I suggest the following entry:

@online{pict,
 author  = "Wikimedia Commons",
 title   = "Plaques of Lambda Phages on E. coli XL1-Blue MRF",
 year    = "2007",
 urlseen = "03-02-13",
 url     = "https://commons.wikimedia.org/wiki/File%3aLambdaPlaques.jpg",
 note    = "File: \ttfamily{LambdaPlaques.jpg}",
}

My suggestion based on the described rules here: https://en.wikipedia.org/wiki/Wikipedia:Citing_Wikipedia#BibTeX_entry
