Hi RDME07,

This feature is not available in our theme. You have to make code customization. Go to theme folder -> functions.php on line no 143 and 144 you will see this code.

	add_image_size( 'slider-narrow', 1038, 460, true ); 		// used on Featured Slider on Homepage Header for narrow layout
	add_image_size( 'slider-wide', 1400, 460, true ); 			// used on Featured Slider on Homepage Header for wide layout

change you slide image size according to your needs. But create a child theme before making any changes on it. After changing the slider size install regenerate Thumbnail plugins and regenerate the images.

Thank you!
