[Plugin: Image Widget] php to hide or remove div for image title

I am using this neat little widget to place a site’s logo in a sidebar rather than the header. But because the css scheme doesn’t make it easy to hide the display of the image title I am getting a border line appearing above the image, when leaving the title blank. No matter how specific I am with the css, either all box borders disappear, or this line appears.

Would you give me a steer on how to stop the widget title from appearing, presumably an echo line somewhere.

Thanks
