Expanding Pictures

I used to be able to take large formatted photos from flickr and embed them in blogger. It would give me a full shot on the page which, when clicked, would expand in a new window to the full sized image. Example here:

A few weeks back it changed and now if I link to a large formatted shot, it embeds the fully large shot then cuts it off to only show a part of the picture. Now I'm having to embed a medium formatted picture. Example here:

I'd really like to be able to revert back to the way the first example is displayed (full shot with a link to the expanded large format).

Any tips or ideas for how I get back to that or what was changed that broke it?
