Putting portrait and landscape orientation in one row?

You could place the photograph on a background of the desired size and save it as a new mage and post it?

If you look at the HTML code, it’s not the same for the errant photo(s). The ones above are in a div with the class “photo” which has CSS to float: left”, but the one at the bottom is not in that kind of div and has no float: left assigned to it. The bottom two photos both should be in separate divs with the class photo — not inside one div like that.
