Start by dealing with errors. You have MANY. Look at the javascript console in your browser.
Your server sends 404 (not found) errors for MANY files.
And you didn't load a plugin called responsiveSlides.
FWIW, I wouldn't use jQuery to make images equal height. If I had to make images equal height, I would use flexbox CSS.
But I would avoid making images equal height (in the browser) at all, because it will distort them. Seems an especially bad idea for a site presenting architecture. The images should be cropped for proper aspect ratio to fit where you want them.
