Hans &amp; Friends

“Replace External Images” lets you import externally hosted images used in post content directly into your WordPress media library — either one by one or now with the new bulk import feature across multiple posts at once.
The plugin automatically replaces external URLs in the content with local media URLs, shows a live progress view, supports any image host, and updates featured images where needed.
Ideal for: 
– site migrations 
– pasted content from other sources 
– cleaning up hotlinked images 
– processing many posts in one go with the bulk importer
