(edit)
Alternatively try this;
Open Chrome
Click on the rows of small horizontal lines located in the top right hand corner
Then click on "more tools"
Then on "Extensions"
Then "Get more extensions" if you already have some, e.g. Ad Block.
Type in "Photobucket embed fix" and hit the return key
A link to "Photobucket embed fix" extenstion should appear. Click on it and you are done.

Failing all that, go to "help" and find out how to load 'extensions' and then add extension "photobucket embed fix".
