A strange thing happened today. I used to have an image in my sidebar with a caption attached but below the image. Well, I changed the caption and copy/pasted the new html code and now the image shows up with the code. After many attempts, I replaced the new code with the old one that used to work. Now, it does the same thing. I've deleted my cookies and restarted the computer and tried it all again. It's still showing the code.
Here's what I'm trying to do. When I uploaded my photo to the media library, I added the caption to the image (since WordPress allows you to do that). What this created was a nice little gray box around my picture and caption. I want to have that same look, even if I have to go about it a different way.
