Change Product Image Sizes in WooCommerce Easily
Explanation
To change the size of your product images in WooCommerce, you can use a simple function that adjusts the width of different types of images. Here's what each part does:
- Single Product Image: This is the main image you see on a product's page. The code sets its width to 600 pixels.
- Catalog Image: These are the images you see on product listing pages, like category pages. The code sets their width to 300 pixels.
- Thumbnail Image: These are the smaller images, often used in galleries or as additional product images. The code sets their width to 100 pixels.
After changing these sizes, it's important to regenerate your thumbnails. This ensures that all your images are resized correctly according to the new settings. The code checks if the regeneration tool is available and queues it to run.
Finally, to make sure everything works smoothly, the code flushes the rewrite rules. This step helps WordPress recognize the changes and apply them properly.
Code
// Function to change WooCommerce product image sizes
function wp_dudecom_change_woocommerce_image_sizes() {
// Set the single product image size
update_option('woocommerce_single_image_width', 600); // Width in pixels
// Set the catalog image size
update_option('woocommerce_thumbnail_image_width', 300); // Width in pixels
// Set the thumbnail image size
update_option('woocommerce_gallery_thumbnail_image_width', 100); // Width in pixels
// Regenerate thumbnails after changing image sizes
if (class_exists('WC_Regenerate_Images')) {
WC_Regenerate_Images::queue_image_regeneration();
}
}
add_action('after_switch_theme', 'wp_dudecom_change_woocommerce_image_sizes');
// Ensure the changes take effect by flushing the rewrite rules
function wp_dudecom_flush_rewrite_rules() {
flush_rewrite_rules();
}
add_action('after_switch_theme', 'wp_dudecom_flush_rewrite_rules');Instructions
