No it's not just you.
Many of us used Photobucket for picture storage, editing & posting, and it was either Free for a low number, or small amounts like $20 per year for thousands of pics.
Now without warning, Photobucket changed their rules & they want $400 per year to be able to post pics through their service.
If you don't pay that price, your pics will be replaced with what you are seeing.
