Thanks so much.  I'll paste the AS comments on that talk page, but the tourette collage is for me, on Tourette syndrome.  It is the only image having to do with TS I could find in the public domain, so I went with it.  I didn't realize we could create our own:  can I ask someone to do that?  I just want something colorful on the article, to offset all the pictures of the old men.
