Help!

I’m a photographer using this theme and I love it so far, but can anyone tell me if there’s a way to prevent text posts from showing up in the slider on the home page?

For example, right now I have 5-6 posts with multiple images in them and love how the slider looks, but if I make a text only post it puts a grey box into my slider for the text post, is there a way to exclude those posts from the slider so only my images show up?

Hopefully I explained that well enough, appreciate any help!
