screenshot - How might I obtain a Snapshot or Thumbnail of a web page using PHP?

Question

I need to create Snapshots / Thumbshots / Site preview a-site.com.

There are some site as thumbshot.org that meets with I need. But I do not want to use an external service, not to depend on others for my project (What would happen if they close the site?)

For this reason, I am looking for some project to let me do this.

Any idea?

On windows you can use GD's imagegrabwindow() function.

Edit: The help page actually shows you how to grab a screenshot from IE.
