Property Image slider

Hello,
Can I change the property detail page so that the property images are not a slider and displayed more as a gallery style.

This would be a single image with thumbnails below that the user clicks on and it then replaces the larger image?

If not then I have another question, the modal does not currently work and the image does not open as a modal but simply opens the image within the same browser tab replacing the website page.

Thanks

Lee
