This is a Firefox or Chrome add-on that will allow you to view the blocked photobucket links.  Only devices that have the add-on installed will be able to see the photos, so if you have home and work computers, or a smart phone, you'll need to put the add-on on all devices. 

On Firefox, click on the three bars on the right side of the screen, then click on add ons. You will then scroll down and click on "See More Add-ons".  Search for "Photobucket Hotlink" and install.
The above instructions worked for me.  If you are using Chrome try these instructions:
"If you're using Google Chrome, go to the three dots on the right side of the screen and click them. A drop down should appear. Hover your mouse over "More Tools," and when the next drop down appears, click on extensions. Go to the link towards the bottom that says "Get more extensions." In the search box, type "Photobucket Fix," and hit enter. Click the install button and once it's done, you should be able to see photobucket pictures again".

At least for those with this add-on, so many threads in so many forums become useful again.  Thanks to Daryl D on Britbike.com for bringing this to our attention.

I added it to Chrome. Now to see if it works.

You probably know of a post that has blocked photos, but if you don't - locate a post where the photos are blocked - then download the add-on, go back and check the post.

I have a somewhat large post on britbike.com with a lot of (blocked) photobucket pics.  I went to that post and all the pics were visible.
