This is gross, it could be a onetime fee.
It's hard to remember with all the ownership changes, but the Photobucket era was really a different time, of "it's your data, you're in charge, and we give you maximal control of it" - people would upload there to post elsewhere, and I recall they ran ads to monetize. But this era had the ethic that uploading was expensive, and you'd maybe want to do it once and have control of your stuff after that.
Now we have photo hosting services that barely work on the web (iCloud), or work only within a walled garden (Instagram), and I do miss the "it's your stuff, we're just a website" kind of attitude from the mid-2000s.
I, too, miss the time when I was a kid and people would give me free cookies. Now as an adult I have to buy my own cookies.
