i think it's because of pruning old images uploaded directly after some time. you see all the "attachment deleted by admin" in all sorts of old threads. not enough storage or something. rather annoying if you ask me ... good amounts of online storage for VPSes and such aren't that expensive as far as I know. My non commercial site currently has 14GB used, 107GB available. but maybe the images take more size than i'd expect...
also, no forced HTTPS? ha ha nag nag. but there is https support, good
if anything I should make my own easy image hosting site rather than whine about it here
great looking bows
