Inserting Images & Caption — Not displaying correctly?

Hi,

I’m almost satisfied with my theme but there is one flaw. When I am writing a post and I add an image (via the “add image” button) and write a caption it doesn’t display correctly on the page. Under the visual tab everything looks fine, which you can see here: https://therawblogger.com/wp-content/uploads/2009/08/visual.JPG

However what actually shows up is this: https://therawblogger.com — There’s no background behind the thumbnail, it’s not centered & the caption doesn’t look right. I switched to the default theme and it works fine, but there’s a larger problem I dislike with the default theme. The centering thing isn’t a big issue, I can go to the html tab and add that in manually– I’m not sure if I could add in the rest, I don’t know how.

So what is wrong here? Can I add something to fix this? I’ll show the css below:
