Oh yeah I’ve seen this on many Genesis themes. I think its because some images scale differently than others depending on the size. So if you have a large vertical image and set the image size to 900px wide, it probably won’t stretch to 900px. WP does this to avoid your images from looking to distorted and stretched.
You could probably add a clear: both to the paragraph tags, but just in your content areas.
.entry-content p {
clear: both;
}
I’m sure that will work, but it may affect other areas of your site if you plan to have images float left next to a paragraph that is designed to “clear”
.
