html2image for enterprise linux

We have now updated the html2image tool for linux to support Enterprise linux versions such as Redhat enterprise linux 3 and 4.

The newversion also updates the document on how to use html2image with Xvfb, an in-memory X server.

With Xvfb, it is possible to run html2image on a headless server without display.

Feel free to get it from html2image homepage.
