Safari 5.1.1 doesn't load webpages correctly

Every since updating yesterday to Safari 5.1.1 my webpages don't seem to be loading correctly. For instance, when loading NYTimes.com I get all of the text, but in each picture there is a "?". When clicking on an article, the webpage doesn't load correctly. See the picture below:

On some webpages, such as store.apple.com, it says the server cannot be found and doesn't load the page at all, but in Firefox it will fly right up. I know Apple provided the following solution (http://support.apple.com/kb/TS3408), but none of these have worked. I have reset safari as well and that doesn't seem to work. This is also happening on my iPad as well. Is this something to do with the update to iOS5 and the new Safari browser or is it something on my end? I have owned many Apple products, but this is the first time something like this has happened on a repeated basis. Anyone have any ideas?
