Inserting images' previews linked to original image is very simple with this plugin. Like Quick Image Preview plugin it can insert images into your document but does it faster and more simple.
You will only press the button on CKEditor's toolbar and select files in open dialog (multiple files select is still available), and they are being uploaded to the server.
The server side script will create small previews of configured site for them, and they will be inserted.
By default this preview will has a link to original image and automatically integrates with AJAX gallery scripts like LightBox or FancyBox, but you can change the template as you want.
Also if you would like to format all inserted images with wrapping them with some HTML code, you have this feature to. So maybe you want to show the uploaded images like a gallery (with grid), you will be able to do it.
