Description
Default Image Assistant allows you to assign a default featured image for each public post type in WordPress.
If a post has no featured image set, the plugin automatically loads the default image you assigned.
Perfect for:
* Blogs that require a fallback image
* Custom post type archives
* Editorial workflows
* Sites with large content teams
Features:
* Visual Media Library selector for each post type
* Clean and modern card-style admin UI
* One-click remove default image
* No front-end bloat—only loads when needed
* Works with all themes (including block themes)

FAQ

Does this overwrite posts that already have featured images?

wp_get_attachment_image()and lightweight filters.
No front-end scripts or styles are loaded. -
Can I assign different default images for custom post types?

Yes. Any public post type registered via plugins or themes is supported.
-
Does it support block themes (FSE)?
-
Yes. It works regardless of theme type.
