Text & Image Issue

I’m having a problem with an image loaded into a dynamic text box. It loads into the box fine, but then the text below it doesn’t start below the image and instead runs along the side of the image.

Is there a way to force the text to start where the image file ends?

I need the “Posted by…” part to start right below the image, but I can’t figure it out. I’ve tried using linebreak tags, but nothing is working. Are there some major tags that I’m missing?
