Can’t get text below image…

…it wants to wrap around the image, but I don’t want it to. I would like all the elements to line up vertically, each below the previous one, like so:

text
image
text
image
text

I don’t care if the images are centered or flush left.

Here is the URL, so you can see what I’m talking about:

I’ve tried a bunch of stuff and nothing seems to be working. I can post the existing code if that would help.

Thank you!
