/*
This routine creates a pop-up window, and ensures that it takes focus. It is 
intended to be called from an anchor tag. The new window will resize itself to 
the optimum size, so we make it as large as the largest required window to
overcome bugs in various manifestations of various browsers.

Calling sequence: <a href="a.jpg" onClick="return openLargeImage('a.jpg','Caption');">

The first parameter is the URL of the image to be opened, and the second 
parameter is the caption for the image which is displayed in the window title
and in the alt property of the image tag.

Note that the calling sequence will simply open the image in the main window if
JavaScript isn't enabled.
