LH Browser Shots

Add screenshots of remote wesbites directly to the wordpress media library, either enter the site url in an onsite input box or click a bookmarklet.

This plugin allows you to create duplicate images in the media library, rather than having to create a new copy of the image and upload it to WordPress again.
It works by copying the post and its metadata into a totally new file in the media manager. Any changes you make to the new copy of the attachment — updating the caption or cropping, for example, will only be applied to the new attachment, not to the original.
This is useful if you want to edit or crop an existing image without effecting the original
To use, go to the Library tab and you will see a copy file link below each media (this will only appear in list view, see faq)
