Losing a picture hosting site and association with past posts with no way easy way to recover is tragic. The amount of shared info that has been lost cannot be replaced.
Did you start an account on flickr or free trail?
I'm currently using smugmug which is 7 monthly or 55 annually, no free accounts. I have duplicate free account with Imgur. Both of these mirror original photobucket account, which most have heard that story.
Fortunately photobucket changed thier policy and older pictures at least show, likely temporary (unless like many account was deleted in response to pb fiasco). I look at thier attempt to regain trust like someone jumping off a cliff and trying to swim back to the ledge.
Thankful old photos show but do not use to post new pictures.
Some of my older posts where thread wasn't locked Ive update urls- older locked threads show until photobucket closes.
Flickr (which now owned by Smugmug, acquired financially troubled Flickr awhile back) is 7 monthly or 60 annually. They surprisingly still offer free hosting service.
Either service offers trial period to check features which are simular. One of the things that attracted me to smugmug is part of the url contains original file name, easier to relocate.
Seems easier to get different share links, though bbcode copy/pastes picture, its also makes it clickable to album so usually strip out url string.
Issue obviously is on forum posts if host site is changed (site closes) the linked photo url needs to be changed. On older locked threads that's impossible, and threads that are not locked, it to say the least painful to update the picture urls.
