I looked for an image for decorating the main page of my website. I found a great image in Wikipedia. The license allows me to use the image, but, I must give credit to the creators (which includes their name and a link to their Flickr page).

My question is: what is the best way to give credit about the image, such that the page design will not be harmed?

In case it matters: my page is very simple - it contains only the image (floated right), a heading, a small amount of text, and some links. But, my question is more general and probably applies to many different websites.
