Can I change Hover Image?

Try to add the following PHP code snippet to the child theme functions.php file to do this

function woodmart_hover_image() {
	global $product;

	$attachment_ids = $product->get_gallery_image_ids();

	$hover_image = '';

	$id = end( $attachment_ids );

	if ( ! empty( $id ) ) {
		$hover_image = woodmart_get_product_thumbnail( 'woocommerce_thumbnail', $id );
	}

	if( $hover_image != '' && woodmart_get_opt( 'hover_image' ) ): ?>
		<div class="hover-img">
			<a href="<?php echo esc_url( get_permalink() ); ?>">
				<?php echo ( $hover_image ); ?>
			</a>
		</div>
	<?php endif;

}
