Follow these steps to find your personal Facebook photo upload address:
Navigate to your own profile page on Facebook by clicking your name in the blue bar at the top of the page. This should take you to your "Wall," the first of the tabs across the top of your profile page, just below your status.
Below the tab bar is the box where you can update your status. Below the box where you type, you will see "Attach:" and a list of several icons including photos (1). Click Photos. If you don't see photos here, click the arrow to open the "more" menu and you should find it there.
Now you will see three options: Upload a Photo, Take a Photo, and Create an Album. Click the first option--Upload a Photo (2).
Now you will see a box to browse for a file on your computer, but just below it, there is a link titled "upload via email" (3). Click this to learn your personalized upload email address. There is also a link to have it emailed to you. Be sure to read the information from Facebook about using your upload email address.
Now you can save this address to your contact list and to your favorite photo organizing software for easily posting photos to Facebook. When you email pictures from this address, the subject line will become the caption for each photo when it is posted on Facebook, and pictures will go into a "Mobile Uploads" album. Once the photos are on Facebook, you can move them to a new album, customize captions, tag people, and so on.
Your Facebook upload address can be used to post videos, too.
