Whether in bulk or on an individual basis, a DOM Exception 11 error (or whatever it is) pops up, and an Internal Server Error shows up instead of the image I wanted to upload.
And since this image has reminded me of it, my own personal image gallery hasn't updated since March 27 (26, if I click the All Images Tag). It seems that my images stay if I upload them to a specific gallery, but they only stay in that specific gallery, sadly. No action on the All Images front.
(I would have put the second glitch specifically in the title, but character limits kept me back.)
