*
* Purpose: Allows multiple pictures to be flipped through on a page.  When click either pops up a 
*          link or email... see options below.
*
* Example:
*        <table border=0 cellpadding=2 cellspacing=0><tr><td align=center>
*          <a href="javascript:dolink( )"><img src="/images/construction.gif" name="PicFade" style="filter:revealTrans(duration=3,transition=23)" width=220 height=70 border=0></a></td></tr>
*        </table>
*
* Extension: To use this function for different pages, simply take the first three statements
*            that define the different arrays out of this file and place them on the pages you
*            want to display the fader on and include this file excluding the three array declarations.
*
