remove image code

I really like the simplicity of using this plugin but do not have it in use on the above site because it insists on placing a goofy-looking icon in place of the “linked image” that none of my posts contain. I would like a simple, easy to follow solution to this so that just the text of the most recent post appears on the page.
I know, boring and dull. Too bad. Can this plugin accommodate posts without images, or is there one that someone knows of that will?
