WooCommerce产品页面产品图片不显示求助：移除functions.php自定义代码后图片仍无法恢复

Hey there, let's work through this issue together—this kind of "changes not taking effect" problem is super common, but usually easy to fix with a few targeted checks:

• Clear every layer of cache first
  WordPress (and your browser/CDN) loves holding onto old cached content. Start by purging your site's caching plugin (like WP Rocket or W3 Total Cache), then clear your browser cache (hit Ctrl+Shift+Delete on most browsers), and if you use a CDN (Cloudflare, etc.), purge that cache too. 9 times out of 10, this fixes the "code is gone but the change isn't showing" problem.

• Double-check your theme's WooCommerce settings
  Many popular WooCommerce themes (Storefront, Flatsome, etc.) have built-in toggles for product images in the customizer. Head to Appearance > Customize > WooCommerce > Single Product (the exact path might vary a bit by theme) and make sure the product image display is turned on. It's possible you accidentally toggled this off before, and it stayed that way even after removing your functions.php code.

• Inspect your functions.php for leftover code
  Did you remove all the code you added to hide images? Sometimes a stray line or a half-deleted snippet can still cause issues. Open your child theme's functions.php (always use a child theme, by the way!) and scan for any code related to woocommerce_single_product_image_html or hooks that might hide images. Also, make sure there are no syntax errors (like missing closing brackets) that could be breaking other parts of your site.

• Check for conflicting CSS
  Maybe your original code added custom CSS to hide images, and that CSS is still lingering somewhere. Right-click the empty space where your product image should be, select "Inspect" (Chrome/Firefox), and look for CSS rules like display: none; or visibility: hidden; targeting elements like .woocommerce-product-gallery or .woocommerce-product-gallery__image. If you find any, remove them from your theme's "Additional CSS" section (in Customize) or style.css file.

• Test for plugin conflicts
  Disable all plugins except WooCommerce, then refresh your product page. If the images show up, re-enable plugins one by one until you find the culprit. Sometimes niche WooCommerce extensions, custom code plugins, or even security plugins can override image display settings without you realizing it.

• Verify WooCommerce image settings and regenerate thumbnails
  Head to WooCommerce > Settings > Products > Display and check that your "Single product image" and "Gallery thumbnails" sizes are set correctly. If the images were hidden for a while, they might not have been generated properly. Install the Regenerate Thumbnails plugin, run it, and see if that fixes the missing images.

If none of these steps work, feel free to share a bit more details—like your theme name, any recent plugin updates, or a snippet of the code you originally removed—and we can dig deeper.
