Highend responsiveness issues

Hi!

I like your Highend theme a lot, but I’m having some issues with it’s responsiveness.

My site is http://bsgaleria.mx/wordpress. I’ve set up a “Page Title with Background Image” up on all my pages, and it looks fine on my desktop browser (if it’s open full size). But the images do not resize correctly for different display types (i.e. mobile displays or a smaller browser sized-window). For example try http://bsgaleria.mx/wordpress/inicio/obra-original-y-grafica/ or http://bsgaleria.mx/wordpress/inicio/fotografia/ (i.e. compare the right side of the images in a desktop browser vs. a phone). I’ve tried turning on and off the Visual Composer Setting “Disable responsive content elements”. But it doesn’t seem to help this particular situation.

How can I fix this?
