3rd party hosting

Almost every post i see that has pictures are blocked with a message that i need to update my account to allow 3rd party hosting. But.... I have yet to find where I make that change on my account or preferences.
Do any of you know how to do this or what the issue is?

Are you referring to the ones that also say Photobucket? If so, the problem is wth Photobucket themselves and changes they have made.

Yes I think they are photo bucket. Thanks for the info.
