image not centered

[Joel Schiff]

When I insert an image into a float box, I have the cursor to the left  
of the Figure #, and press return, insert the image, but the image  
always ends up on the left hand side of the box, even in the dvi file.  
Of course I want all images centered on the page but cannot get this  
to happen.

I must be doing something wrong as this is very basic. Sorry if this  
has been asked before.
