Paul, it might be a bandwidth/storage issue with Photobucket. I had the same thing happen. Once you have a bunch of pictures and reach their free space/bandwidth limit, then you have to pay to keep everything going. After so many views of your pics (bandwidth use), people can't see the pics. I think that's what happening. I'm not expert, but if anyone is out there, please chime in and correct me on the specifics. That's the only reason that I can think of that it's happening.
You can fix this by upgrading your Photobucket account (they should have sent you an email warning you about this and how to fix it) or you can switch to a different photo storage website.
I run an outdoors blog, so I need to have my pictures showing, so I upgraded my account. I pay for the cheapest option and it's more than enough storage/bandwidth. It's about $20 per year or so, I think.
