If this does get implemented, of course it should be an option, but taking it a step further, I’d love for it to be a 3-way option between showing the full size image, showing the text, or showing a small thumbnail to give you an idea of what you’re clicking on. Personally, I think the thumbnail would be the best solution, as I don’t love the idea of just anyone in the comments being allowed to post giant pictures on my screen as I’m scrolling through, but I also want an idea of what I’m clicking on before viewing a picture. A small thumbnail seems perfect for that.
