So this is pretty cool: A simple work-around is using the 'press Shift on the thumbnail to preview image' feature to see it. So even though the system will blacklist it on the post and pool pages, you can still see the image if you just preview it like that. A handy feature on its own, but now it's useful for a new reason :]
Speaking of which, one other thing that might be cool is 'press Shift multiple times to cycle through zoom-in levels of the full image,' like you can do when on the actual image screen by clicking it. That'd be great for some images because sometimes they just aren't big enough (especially if they've got text/dialogue). It could even potentially lead to folks opting to just preview everything instead of opening a hundred tabs. Interesting to think about~
