Looks like Photobucket went and screwed everyone yesterday or today... they updated their terms of service with no notice or announcement and changed it so that free users cannot use Photobucket and link to it from forums etc. In fact, the only way you can do this is to pay them $400 per year... yeah right!

I'm in the process of deleting my account and will find an alternative...

It does mean a lot of work to go and update my Kat thread so I'm not sure how soon I'll get to that or if I will, but new stuff will be right once I get an alternative sorted.
