IMO, the important thing is to NOT use any of those hosting sites to STORE your images. From what I have gathered that's what so many were doing with photobucket, and they lost them. This infuriated some, but I never trusted them to store mine anyway, especially for free, so I lost nothing. Good riddance, to them (photobucket) I say. Store your images somewhere secure and just use jpgbox as a guest. I use our desktop Apple/Mac to store mine. I suppose they go to "the cloud", whatever that is. It's worked perfectly for me, for a great many years, so far.
But, maybe I've just been lucky.
