custom fields, what is it for?

[usagi]

when you edit a category, there is an option for adding a field...what is that for

[SMFHacks]

Add extra's fields when uploading an image, and the display image page.

Allows you to require extra information if you need to.

Maybe for example you would want a section called image location and in that section they would place the location the image was taken.
