Since it took me a second as well, i thought, i’d better share this with you:
If you want to see a bigger version of an image, you don’t need to open the thread (in fact it wouldn’t even help).
Just click on the small tile with the image and a bigger version will appear.
You don’t need to hit the small image icon. The general image works aswell!
Oh, thanks, but thats what i meant – bad wording i suppose ._.
