I have a client that I'm developing a site for and he needs to be able to upload and manage his own pictures. He has a small car lot and wants to be able to put up pictures of the cars he has for sale with description and price. He wants to be able to do this himself but is a car salesman not programmer so it needs to be easy.

I need to be able to make it a part of the regular html site I've designed for him. Would it be better if I designed it in Word Press or Drupal or is there something out there that I can incorporate into the html site?

Thanks!
