Plugin has skewed layout & doesn’t show image

Here’s a link to the blog I’ve been working on.

I tweaked the theme Batavia to create the layout and added sticky-image plugin, but now the images are not only coming up, but it’s completely knocked it out of alignment…

when I upload the image to the wp-content/images folder as instructed in post mode, no matter what the name of the image, when I view the page and mouseover where the image should be, it says in the bottom bar the image is called 4.pic.jpg or 5.pic.jpg.

If I click on the box where the image should be, I get an error: imagejpeg(): supplied argument is not a valid Image resource in <b>/usr/home/www/…/wp-content/plugins/sticky_image/sticky_image.php</b> on line <b>251</b>

Anyone have the faintest idea WHAT I am doing wrong here?
