Here is an entry that has lots of stuff in it. It has text in the body, but then also an extended entry.
here is my photograph.
Underneath the photo I have a caption. All photos have to have captions and they must be visually different than the text entry.
Now, I'm going to insert some video from youtube of my dog walking on ice.
Again, the video needs a caption so the reader knows what's going on. Here is my dog trying to walk on ice, but not doing it very well. Same style as the photo above so that it is consistent.
