Take a photo of something up close. If your camera can take macro shots do that. Work on getting the focus exactly right, it makes a huge difference.
It is surprising how much you see when you can really study the detail of something you might see every day. Macro photos also make very unique and interesting background images. Could you take several and offer them on your site? Never a bad idea to offer a few freebies when you can. Especially when the freebies really are free and really are worth having.
