Watermark Sizes

windwood

I've set up a site and there are many images posted. There is a watermark in place, however, it seems the watermark does not want to show on portrait oriented photos. I'm guessing the reason for this is the size of the watermark. Therefore, is there a specific limit to the size of a watermark?

Here is the site in question.

Specifically, and exactly, show us a photo that won't watermark?
