I don’t normally post blog articles that are reposts of other content, but this email thread answered a question that I’ve struggled with, which is how do you render a web page and save it as an image.

It’s one of those things that seems like everybody wants it, but no one has quite figured out. And the various “services” like thumbshots all feel kinda “seedy”, I am always expecting to see advertisements for viagra stamped on top of the screenshots and other questionable business practices.
It seems like you should be able to have the pages be render inside of a library such as WebKit, but I guess rendering is very intertwined with monitor displays and resolutions etc.
I have a research projects that aggregates info about people, events, and organizations and I’d love a better solution for linking in screenshots of the organizations and individuals site. Here is an example using the thumbshot service for now..: http://www.hightechcville.com/organizations/318-worrell-water-technologies

Khtml2png – http://khtml2png.sourceforge.net/ â€œKhtml2png is a command line program to create screenshots of webpages. It uses libkhtml (the library that is used in the KDE web browser Konqueror). In khtml2png 2.0.5 to 2.5.0, “convert” from the ImageMagick graphic conversion toolkit is used to create the output files in various image file formats. 2.6.0 and future development will use the built-in conversion of the Qt library.â€ â€“ from the Khtml2png website
Pearl Crescent Page Saver – http://pearlcrescent.com/products/pagesaver/ â€œPearl Crescent Page Saverâ€ is an extension for Mozilla Firefox that lets you capture images of web pages. These images can be saved in PNG format or (with Firefox 2) in JPEG format. The entire page or just the visible portion may be captured. Options let you control whether images are captured at full size (which is the default) or scaled down to a smaller size. Page Saver uses the canvas feature that was introduced in Firefox 1.5.â€ â€“ from the Pearl Crescent Page Saver website
