Since Photobucket started charging users money to display links to their (many) photos, a lot of enthusiast forums have lost access to valuable pictures, and embedded pictures stored on Photobucket are no longer visible.
Fix for seeing Photobucket pics
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.
For FireFox users, click on the three bars on the right side of the screen, then click on Add-ons. Click Search for "photobucket hotlink" and click install. Same result.
