UPDATE:

This guide is not functional at this time due to changes to OAUTH 2.0 on the Facebook.com. See: http://developers.facebook.com/docs/reference/javascript/FB.getAuthResponse/. I might revise it in the future, but right now I’m disgusted by of all these Facebook API changes.

Here’s an example of a Flash SWF that allows you to browse images (and swfs) from your computer, then post the uploaded images into your Facebook Photo Album using facebook-actionscript-api to http://code.google.com/p/facebook-actionscript-api/.

First, click the Login To Facebook button if you are not already logged in.

Then, an Upload Image button will appear. Click it and upload something.

Once the image is uploaded, another button labelled Save To Photo Album will appear. Click it to upload to your Facebook Photo Album.

Here’s a brief overview of how the code works, along with links to more detailed documentations and the link to the source FLA.
To post to your photo album, you can just use:

Facebook.api('me/photos', callback, params);

where the parameters contain an image field of a Bitmap object, a message string (which will appear as the caption of the photo in Facebook), and a fileName (this will not be displayed in Facebook and you can use generic name). Example:

	var params:Object = {image:myBitmap, message:'My Example Photo', fileName:'FILE_NAME'};
	Facebook.api('me/photos', callback, params);

The process of browsing and uploading files is explained in:
http://www.permadi.com/blog/2010/06/flash-using-filereference-and-php-to-upload-files-to-server/ (note: you do not need the server component since you will only be uploading to Facebook). FileReference is used to allow user to browse and upload images. Note that FileReference requires Flash player 10.
