How deals the Bridge theme with image ?

Hi there,

I presum that there is some Bridge theme’s users, and I hope that some of you can help me on an technical question.
In a way, it’s a presale question, I found the theme nice, but need to know what’s inside before buying it .

It’s about how Bridge deals with images. I’m photographer, I use a lot of image , so It’s important for me.

Does it load image by using the new wordpress fonction SRCSET like WordPress now does ? or does it just load the picture as is ? (http://wpbestpractices.com/wordpress-4-4-responsive-images/).
In an other way , if I want to use a 5000px image large, asking to play it on a Smartphone, will it load the 5000px image, or will it use the SCRST wordpress fonction to load a smaller image ?

Other question, : Does the theme use a Lazy Load fonction for image ? If not, If I want to use the plugin ” BJ Lazy Load”, will it work with Bridges images ? Will they be lazy loaded ? or not ?

Thank you !
Alexandre
