Link images & remove hover

Hey, thanks for the wonderful plugin!

I can’t seem to figure out these 2 issues though:
1. I have set each image with a link, but clicking on the image still leads to the image itself instead of the link.
2. I can’t remove the on-hover gray screen for some reason?

Here’s my site:

Thanks in advance 😀
