I found some nice images on Flickr using the advanced image search to show only those that are creative commons licensed; I want to use the images in a commercial website I am building.

One of the images can be found here. The Creative Commons license that is linked to says

Attribution — You must attribute the work in the manner specified by the author or licensor (but not in any way that suggests that they endorse you or your use of the work).

On the Flickr page I don't see anything indicating how to attribute it. Is it enough to give the photographer's name as a caption to the image? Or as a comment in the source of the page? I don't want the attribution to take up too much room or prominence on the site, as it's orthogonal to the purpose of the site (it's not a site about photography, it's a podiatrist's office).

I want to make sure to do right by the photographer, so any advice would be appreciated.
