How to add photo album to Facebook

With this feature, you're allowed to upload one file at one time(mean the you can post only one image or video at a time). But with this tutorial, I will show how to upload more than one images at a time(Add Photo Album). In some reason, the most Facebook users want to post their images as Album, because those images can be shot in only one event or program.

  1. Stand on Status Update click on Create Photo Album  
  2. Brows for your photos that you want to add then click Open
  3. The Album Setting Diaolog pop ups for you to set(Album title, Description, Date...)  
  4. Click Post Photos
