Safari viewing problems

I run OS X 10.6.6 and Safari will not display any images or videos, just text only. I have tried deleting and installing it but it is still the same, text only. How can I get this back to normal?

Safari -> Preferences -> Appearances. Place a checkmark in the box that states: "Display images when the page opens"

No, this does not do anything at all. Still only text, Can anyone else help?

Do you have any Safari extensions or plug ins loaded? If you do, disable them and see if that helps.

Also, I suggest downloading either Firefox or Chrome to see if you have the same problem with those browsers.
