Yup! These are the extensions I use myself. They work fine
Something makes me think the devs did the filtering this way on purpose... it's definitely possible to reroute the file without using any headers on the request... edit: maybe it isn't so easy now that I've dug through the source code. This same method will likely work with other websites so long as you understand how they filter by request...
For those tech savvy and interested, it adds some javascript to every page. Before any request goes out (link clicked, load image, video, etc), it will inspect its header which holds a lot of details/properties.
If it's a request to photobucket, it will do the following:
-check to see if it's an image being linked to
-if it is, do the following:
--grab the user, and create a link to their full media folder
--find the referer property (what URL the request came from), and replace it with the link to that user's generic media folder
This works because they allow you to view any photos as long as you're navigating their site. There's no hotlinking restrictions within their own domain. So if you pretend you are from their own domain, they give it the OK.
