    Photoshop - How to set the background color to transparent?

    JGreg7 Level 1

      I am using Photoshop CS5, and I have a black and white line drawings (electrical schematic).  I wish to turn the white background to transparent so I can take the schematic lines and paste them over a colored background.


      I have tried using the magic wand tool, but it only selects portions of the background.  I want everything that is white, to be transparent.  In Paint Shop Pro, the command was simply to set the palette transparency to a certain color and you were done.  However, I am trying to learn Photoshop, and I am simply unable to find a way to do this.


      I assume this would be a simple task, since it is used extensively in graphics everywhere, I just do not know how to do it.


      Any help would be appreciated.
