Theme Horse

Hi support7,

Yes exactly if you like to change the slider image size then go to functions.php and you will find 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. If your slider doesnot work then first make a direct change in the code.
add_image_size( ‘slider-wide’, 1400, 460, true ); to
add_image_size( ‘slider-wide’, 1800, 564, true ); and then regenerate thumbnails. There may be something going wrong on the child theme. Then your new slider size will be 1800X564. One thing upload the bigger image size than this ( 1800X564) size.

Thank you!
