Customizing Facebook Share Details (title, url, descirption and image)

I discovered a customizable away of sharing a link on Facebook. The URL is as follows:

http://www.facebook.com/sharer.php?s=100&p[title]=Sample+title%21&p[url]=http://hellopodium.com/&p[summary]=Upcoming+talks+in+toronto&p[images][0]=http://hellopodium.com/static/images/facebook.v2.png

If you break that down, you can see the following details:

• s=100 Not sure what this does, but if it's set to 101, the Facebook Sharer will pull in the data automatically from the source
• p[title]=Sample+title%21 The title of the page being posted
• p[url]=http://hellopodium.com/ The URL of the page being posted
• p[summary]=Upcoming+talks+in+toronto The description/summary of the post
• p[images][0]=http://hellopodium.com/static/images/facebook.v2.png The image that should be shown in the feed

This ability was news to me, so I thought I would post it here as a reminder to myself, as well as for you, enthusiastic reader :)
