Go to http://www.openstreetmap.org in your browser. Zoom in to level
13 or better so that the edit button becomes available. Click on edit,
and then select either "Edit Live", or "Edit with Save". Once you have
Potlatch running, on the bottom of the screen is a button that has the
word "Help" on it. Click that button, and a help screen opens up. On
the top of the help screen, click on the word "Surveying". The last
paragraph under "Using Satellite Photos" describes the process for
shifting the photos against the map.

While you have the help screen open, take a bit of time to read the
information provided. Potlatch is actually a collection of fairly
powerful tools, and information on how to access those tools is
available in the help file.

Now, you are probably thinking that it would have been much easier to
simply say "Hold down "Space", and drag the background", but I'm
hoping you and others will actually take the time to read the help
file rather than keep asking those who have read the help file to
regurgitate it for you. Richard went to the trouble to create the help
file, the least we can do is read it.

It's the old "Teach a man to fish" adage...

The real short answer would have been RTFHP. 8)
