Same here its been going on since last year, mines unusable as a paying subscriber.
Had two emails last week wanting me to upgrade to 500+ as they think I am 3rd party hosting and would get ad free etc. It don't help with not being able to open any of my piccies logged in or not on IE.
Other email stated certain services will be stopped and my piccies will be phased out over next 3 months.
Beauty of photobucket is you can upload videos.
If its just piccies pay the $20 per year and use picturetrail. Been with them around 15 years, photobucket used for additional stuff to keep bandwidth down on picturetrail.
There are many others but don't get on with dropbox and free image hosting.
Your ISP may have storage on cloud and allow you bandwidth? Mine just dumps all over the place cant find a thing, unusable.
