Mee toooo. even photos and photo icons seem to blank-- but I am thinking mine might be in the Firefox update. I'm a Mac user.. and Firefox was recommended-- but now I am finding that Safari (unrecommended) works better for graphic display.
I went through a 227 step process to try to get a hub up on making simple photo and graphics-- which wouldn't display on my final look-- so I kept going back to try to fix-- eeeergh. I think I finally got it in.
