Picture Preview of site from link

So I have a whole bunch of links to different webpages and I want to copy and past this link in a text document to create an html. I want to see a thumbmail beside link that is basically a screen shot of the site. So the image source would have to be a html link (I don't want just the http://abc.com because I forget what most of the links are.) This would be an easy way to know what I'm clicking on before I click it. Then that link would bring me to the site. I tried some scripts but haven't found any. Please let me know if you know anything about this. Until then I will keep searching.
