How do i upload photos from a camera to a website such as Facebook using a Macbook?

Question From User - Answers in Comments.

I have a Canon and it's connected to a USB port on my Macbook and everything works great except that you have to save the pictures first on iPhoto and then transfer the pictures to Facebook? Is there another way to do this without saving the pictures first and doing a direct connect to Facebook? It also resizes the images when uploaded to Facebook. Any suggestions? Thanks.
