Photos display 1×1 for posts, then open by my estimate roughly 3×8 at the top of a story. I find it difficult to locate and/or crop photos that look good on the post pages and also okay when the post is opened. They often end up squashed. They need to have a very specific composition to work both ways. Is there a way to make the top photo frame of a story taller? Maybe 4×8 or 5×8?
