详情介绍:
PB Text and Images Placeholder Fallback Suite fills common empty image locations on your WordPress site with a clean, professional placeholder — or your own custom image. Configure each supported location independently from the plugin settings.
Covered image slots:
- Featured Images — posts, pages, and any custom post type (configurable per post type)
- User Avatars & Gravatars — shown when a user has no Gravatar photo
- WooCommerce Product Images — catalog grid, single product, gallery thumbnails, cart, and mini-cart
- Open Graph / Social Share Images — compatible with Yoast SEO, All in One SEO, and RankMath
- Broken Images — Global Catch-all — Optional JavaScript handler for many broken frontend
<img>elements
- Dynamic Text Placeholders — generates SVG placeholders with the post title, category emoji, and category name embedded directly on the image. Each supported post can receive a distinct placeholder generated from its available metadata.
- Initials Avatar Generator — generates personalised circle, square, or rounded avatars with user initials (for example, “JD”). Available in brand colours or a consistent random colour per user.
- Automatic Brand Colour Detection — scans your active theme's colour palette (editor palette, global styles, customiser) and uses the primary brand colour for all generated placeholders. No external requests.
- Category Placeholder Mapping — map post categories and WooCommerce product categories to custom emojis and colours. Technology→💻, Travel→✈️, Food→🍽️, Business→📈.
- Image Health Dashboard — shows posts, pages, and products without a usable featured-image attachment, plus registered users covered by the avatar fallback. Statistics refresh every 10 minutes from the database.
- Fix Missing Images — a dedicated screen listing all posts/pages/products missing a featured image. Select multiple posts and bulk-assign any Media Library image as the featured image in one click.
- ✅ Ships with 8 bundled SVG placeholders at the correct dimensions for each slot
- ✅ Bundled SVG placeholders are each under 2 KB
- ✅ No external calls — everything is self-contained, including dynamic SVG generation
- ✅ No account required — install and go
- ✅ Each slot is independently toggled — enable only what you need
- ✅ Choose bundled placeholder, your own custom image from the Media Library, or dynamic generated placeholders

常见问题:
Does this plugin make any external requests?
No. All placeholder images are bundled inside the plugin directory, and dynamic SVG placeholders are generated server-side using PHP. No data is sent to any external server at any time.
Will this slow down my site?
The plugin is designed to be lightweight. Bundled placeholders are SVG files under 2 KB each. Dynamic placeholders are generated server-side and use browser caching headers. The optional broken-image handler loads a small frontend script only when enabled.
What are dynamic text placeholders?
When enabled, instead of showing a generic grey box, the plugin generates a unique SVG for each post containing the post title, category emoji, and category name. Each supported post can receive a different placeholder based on its title and category information.
How does the initials avatar generator work?
The generator creates a personalised avatar with the user's initials (first letter of first name + first letter of last name). The colour is consistent per user (based on a hash of the user ID) or uses your brand colour, depending on your setting. Works for registered WordPress users. Anonymous commenters use the configured static avatar fallback.
Does it work with WooCommerce?
Yes. When WooCommerce is active, the WooCommerce slot appears automatically. It replaces the built-in grey box placeholder across the shop catalog, single product pages, gallery, cart, and mini-cart. Optionally, each product can show its category emoji and name on the placeholder.
Does it interfere with Yoast SEO / AIOSEO / RankMath?
No. For the Open Graph slot, the plugin provides a fallback URL directly to those plugins via their own filter hooks. It only outputs a generic <meta property="og:image"> tag on sites where none of those plugins is active.
What happens if I uninstall the plugin?
The plugin removes its settings, legacy broken-image counter, and cached dashboard statistics. It does not delete posts, media, users, or featured-image assignments.
