This is a photo I used from Morguefile.com, a website where people post pictures they've taken and are willing to share with others. It is especially handy if you want to paint/draw a picture of something to which you don't have access. Because I live in the desert of southern Arizona I use MF on occasion when I need certain plants that don't grow here or an animal whose habitat is elsewhere, etc.
WetCanvas.com is another wonderful resource for many things art wise. They have a photo reference file that is quite good, that is, the photos are taken by people who know that lighting is important and what goes into a quality photo. They also have much other art-related information.
Both these sights are free as are the photos.
