 Two different abbreviations used in this script:
   - image name, usually corresponding to the linked page name
   - rollover state, onMouseOver = ovr, etc.

 First argument must be the RELATIVE path from the site root to the
 navbar images directory, and the first common filename characters of
 the navbar images (ex: './images/navbar/btn').  Remaining arguments
 are all the IMG NAME attributes (recommend to use a 3 alpha-char
 abbreviation for the image name).  For the navbar images, use the
 same image abbrev in the image filenames as used in the IMG NAME
 attributes.  ex: btnhom.gif, btnmap.gif, btnlog.gif, etc.

 First row, define the rollover state abbrev with the filename suffix
 tag in pairs, and also the image filename extension.
 var b=new Array("out","","ovr","-o","dwn","-d","cur","-s"), ext=".jpg"

 example: for Home page, ./images/navbar directory has btnhom.gif,
 btnhom-o.gif, btnhom-s.gif for normal, over, and selected states.

 (My rollover software uses these dash-OneCharacter suffixes,
 otherwise I'd just make the suffix the same as the state abbrev).

 The rollover state abbrev needs to correspond to the function names
 defined after the PreloadImages function.
