I posted the web address in my original post (it's right above the first picture, with the black background). Did a bit of checking and it's ok to use under these conditions:
"All clip art, backgrounds, icons, photo clip art, and any other art created by Dixie Allan, About.com Web Clip Art Expert, unless otherwise referenced, is free to use for personal, educational and non-profit usage for a link back to the webclipart.about.com.

If you use the clip art within my stated terms of use, a link back would be appreciated. An example of a link back is provided below.
