WordPress Custom Fields
What is a custom field?
A little bit of information you can store alongside a

A custom field has two components
A key/value "pair"
Key is the name of the meta data element
eg. image
Value is the information itself
eg. "myphoto.jpg"
Examples:
Key: url Value: "http://www.mysite.net"
Key: my_mood Value: "Happy as a clam"
