How can I get pictures taken down if I signed a model release?

I am a model and recently did a photoshoot where I signed a standard model release after the shoot ended. The photographer posted some of the pictures on his webpage and I am wondering if there is any way I can make him take them down. I am no longer modeling and some of the pictures are a bit revealing (though not explicit) and do not want them to show up when searching my name online as I am now looking for work in the corporate world. Is there anything that can be done? It was a release he wrote himself and I signed after the shoot. Are these things retroactive? I'm desperate to find any sort of technicality that might help me out of this dilemma.
