Share 'Wizard of OZ?'

I have been a wizard of oz fan for years...ever since Dorthoy melted the wicked witch by throwing a bucket of soapy water on her! Any hoo.....I found some WofO images on Flickr that were listed under images free to copy for art work. Can anyone tell me if this is a copyright infringement? I am really excited to make some tags with the images if I can..Thanks, Jean
