Shutterfly locking up IE

Tonight I'm trying to post new pics of Ben, and it seems the drag-drop browser tool keeps locking up IE on me. Last night I went to the sight and found a "We're sorry, we are experiencing technical difficulties", so the sight was completely out of commission. I've tried 3 times now, and I'm about ready to throw in the towel if it locks on me once more. Arrrgh!
