Hi, I'm a total WP beginner. I downloaded this theme for my WP.com blog temporarily while I begin working on my WP.org website, because it allows for full width photographs at 1024. However, they're not coming out larger than 700px maybe? I'm sizing them at 900 px wide at 72 ppi (I don't want them at the full 1024). How can I get them full width? Can't figure it out anywhere. No idea where to enter CSS code should you give it to me. Here's an older post before I downloaded this theme. It did increase my horizontal image size, which was my goal, but I'm waiting to post another blog until I can make the horizontal images bigger. Please help.
