Where can I download stock photos from?

[zadok]

I am currently building a website for a para legal firm. I want to have images on the website but am adamant that these will not be "stolen". Are there any websites where I can download actual free photos.

Currently all the sites I have visited require payment of sorts.

Obviously this website needs to be professional, so I cannot have any cartoon images.

Generally I am looking for pictures of small offices, law-based images, work stations, contracts etc.
