Sometimes we really want to curse at linux don't we . In future we will not even need screenshots , we will be able to actually fell the sites instead.
i use a free software called webswoon to auto capture and resize screen shots then add them in manually for one dir
As with my directory, www.alternativefront.com, I allow the submitters to upload a picture or a screenshot of their site. But it they fail to, I do it myself manually.
Why not just get Dans thumbnailer mod from http://monster-submit.com/ ?? Thats what i use on www.h-log.com and all images are now housed on the server itself.
