Text Wrapping Failure

My images are aligning left and the text is wrapping correctly in the WSYWYG editor but not on the published page. It only works for the first sentence of text and then not for the proceeding paragraphs.

The HTML for the page appears correct:
<img class="alignleft

I’m using the Simple Catch theme. I checked out the style.css and it looks correct:

img.alignleft {
	margin-right: 20px;
	margin-bottom: 20px;
}

I tried changing the margins to 0px in the custom CSS, thinking it maybe was a space issue, but it didn’t work.

Thanks, all.
