Plugin disabling caption links as well as image

Hi, hope someone can help me with this: I’ve created a shop page on my site that has lots of pictures of products. I have inserted captions beneath the images that are links to purchase them. I want to disable the link feature for the actual image but keep the link for the text caption underneath. This plugin seems to disable all links, both for the image and the text. Any way around this? Thanks!
