Thanks for your answer. That’s what I’ve already tried, but the images only distorted thereby.
Is there any way to change the setup of the pane image size?
I think I need to change this section in the theme-setup.php
if (get_option( 'show_on_front' ) == 'page' && !$graphene_settings['disable_homepage_panes']) {
$pane_width = graphene_grid_width( '', 8, 6, 4 );
add_image_size( 'graphene-homepage-pane', apply_filters( 'graphene_homepage_pane_image_width', $pane_width ), apply_filters( 'graphene_homepage_pane_image_height', floor( $pane_width * 0.5 ) ), true);
}
But how?
