You have my greatest sympathies (although I understand that they probably don't help you!).
I have used Photobucket for years, even though I intensely dislike it, and the "service" provided by most image-sharing sites is now really awful generally. Photobucket is nearly unusable from the sheer number of full-page popups and highly-intrusive ads on the site.
I get they need adverts on the site so that the services cab be free, but when that gets to the point that you need an ad-blocker just to be able to upload your images... well, something has gone horribly wrong (and that's not counting the crappification of the images you upload).
I also don't feel I can trust companies that treat users/visitors to their site so poorly, so even if I got a vastly better service for mere pennies a month, I would still not give them any payment details for security reasons.
Anyway, I hope you find something that suits you soon - I really enjoy seeing your work (your Legion of Everblight and Necromunda pix all got saved to my HDD years ago!), and it's a shame that you've hit this block recently.
