Nope. Not working for me.
I sign into my account. Drag an image to that page. Image appears but hovering only allows sizing (+ and -), nothing else.
I can find a URL but if I cut and paste to address/URL window, my account page comes up — which I don't want others to have access to.
What are you expecting to gain by hovering?
What happens if rather than cutting & pasting the URL you simply hit copy? (And under any circumstances, if you don't want others to see your account page, why don't you upload without logging in? Do you gain anything meaningful by logging in?)
