Block Post Thumbnail

This plugin automatically designates the first image block within a post's content as the featured image when one hasn't been manually set. It's designed for content creators and site builders who want to maintain a consistent visual presentation without the extra step of managing separate featured images.

• Automatic Image Selection: The plugin scans a post's content and identifies the first image block, then assigns its image ID as the post's _thumbnail_id meta value.
• Manual Assignment Priority: If a featured image is already manually set for a post, the plugin will not override it, preserving editorial control.
• Simplified Workflow: Reduces the content creation process by removing the need to upload or select an image twice—once for the content and once for the featured image.
• Consistent Site Appearance: Helps ensure posts in archives, feeds, and other theme areas that rely on featured images have a relevant visual automatically.
