Click on Photos in the header bar and then My Photos on the page that appears.

Select Upload Photos and then you can create an album in the pop up window or select an existing album if you have any.  You need to give the album a name and you can also give a location where the pictures were taken and a description of the album.  You can also select the privacy settings of the album here.

Then you can click on Add Files and browse to pictures on your computer.  If you're using a mobile device you can select photos stored on that too.

You can keep on adding files or select View Album.

To delete an album, click on the little arrow in the top right hand corner of the album cover picture and choose Delete Album.

You can also delete photos or move them to another album by selecting a photo and pressing the Options button at the bottom of the photo.
