Image Layout-->Hover Background... how to change/format the photo that comes up?

Hi! 

So I'm tinkering around with a website for my photo portfolio and I've been experimenting with different gallery types to showcase some of the work I've done. It's pretty raw still but I'm slowly building up more galleries and projects.

I'm testing out the Hover: Background layout for my projects. The project title is listed vertically which is fine, but when you hover the cursor over the project title the image is awkwardly cropped, the focus of the image isn't on the right part of the model, and I'd like to choose which image appears when I hover over the project title.

I'm pretty new to Squarespace and this forum, so let me know what additional info I can give. Sorry if this is in the wrong category!

Thanks!

(Image below: when hovering over the Portrait project it clearly curs off my model's head and is using the wrong part of the photo. I might not even want that photo from the gallery, too...)
