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.

Remote Images Grabber

Fetches images from an URL or a piece of html-code, saves them directly into your blog media directory, and attaches to the appointed post.

This wordpress plugin allows visitors to browse posts or pages by their images, displayed randomly on an infinitely scrollable Image Wall. The images link back to the post or page on which they are attached.
Images are powerful. They catch our attention like nothing else. You probably use them in your blog posts to anchor the fickle attention span of today’s readers. Display all these great images on a nice looking page, and your visitors will browse for a while, captivated. Hopefully, one image will stand out for whatever reason and compel the visitor to click it to find out more. And just like that, some old blog post you thought buried by the sands of time has gotten another view, thanks to your Image Wall.
