I ended up using Jquery to remove that piece of the end of the file URL. Seems to work fine. Here is the script if anyone needs it. This works if you set the size of the thumbnail to be 10×10.
$(document).ready(function(){
$("img").each(function() {
var imgsrc = $(this).attr('src');
var imgsrc = imgsrc.replace("-10x10","");
$(this).attr('src',imgsrc);
});
});
