If you see a link you should be able to follow it, other wise it is most likely your security settings and you will have have them changed (these setting are for your computer not the site. Do you see a beige bar at the top of your browser that says "some content blocked..."?)
No, there is no bar at the top. I see only a small red "x", in the individual posts (obviously there should be a picture). Sometimes, more than one x. Just can't seem to figure it out. I have no problem viewing other sites.
Your system may be locking photo bucket. Can you see the picture in my signature? Can you see the aqvitars (pictures by the names) You may have pop up control on. Try right clicking on the picture that you can't see and then select properties, highlight the URL and copy then put it in your browser and see if you can see it on the photo site.
