I couldn't sleep, so I have been playing with the blog. It looks a little different now.
I became very frustrated yesterday when I posted the YouTube video. Even at YouTube's smallest resolution, much of the right side of the video was being cut off. I edited the embedded HTML to make it all fit in the blog body, but then the video was very tiny.
I went into the XML of the blog template and resized everything to make the blog body much wider. Now I can upload photos and videos in greater resolution.
Future photos will be this size:
I'm going back to bed. Later.
