If you're relying on Harper & Row for this proposition, you need to recognize that Campbell v. Acuff-Rose effectively undermines it, both on the facts and in the language of the decision. Its analysis is much closer to weighing the factors equally.
In my opinion even images on user pages should be given a little bit of leeway for this reason. An image which isn't included in any of the articles isn't really in the encyclopedia itself, it's in a temporary workspace which we use to create an encyclopedia.
It's in a workspace that we publish to the entire world over the internet. And don't kid yourself about the temporary here; try removing an inappropriate image from somebody's user page and see how temporary they thought it should be. While I am perfectly happy to be flexible about more restrictive licensing for user page images (no-derivatives or Wikipedia-specific permission), I have yet to see anyone articulate a reasonable argument as to why a copyrighted image would be fair use on a user page.
