This plugin allows you to quickly reattach images to different pages in your WordPress installation. It places a simple drop-down menu in the edit media screen that lists all of the pages in your WordPress site and allows you to reattach the given image to a new page. Note that this plugin only works for images that are attached to pages. It ignores images that are attached to posts.

Use this plugin instead of tiresome saving images from the internet and uploading them to your blog. You learn the value of this grabber e.g. when you need to move your old non-WordPress site with many pictures to the WordPress-based. 
The plugin recognizes images by the presence (jpg|jpeg|gif|png) in URLs.
