Image Hover Causing Content to Move

Hi, and thank you for the plugin.

The problem I’m having has been persistent. I have a developer trying to fix it but she is having no luck.

When hovering over an image, the plugin causes content below the image to momentarily drop lower, as if it’s widening the margin. My site is http://domesticwhimsy.com
