Padding around images

Hello! I love this plugin. I’ve been looking for an Instagram plugin that will display a hashtag feed and this one is the best.

There is only one problem: I can’t change the padding between images. I hardcoded it into the stylesheet, but that messes up the rows and columns.

Is there another way to add padding between images without editing the plugin’s files? Thanks.
