-*   replacePngTags - Justin Koivisto [W.A. Fisher Interactive] 7/1/2003 10:45AM
-*   Modified: 2/11/2004 10:18AM
-*
-*   Modifies IMG tags for MSIE5+ browsers to ensure that PNG-24 transparencies
-*   are displayed correctly.  Replaces original SRC attribute with a transparent
-*   GIF file (spacer.gif) that is located in the same directory as the orignal
-*   image, and adds the STYLE attribute needed to for the browser. (Matching
-*   is case-insensitive. However, the width attribute should come before height.
-*
-*   Also replaces code for PNG images specified as backgrounds via:
-*   background-image: url('image.png'); When using PNG images in the background,
-*   there is no need to use a spacer.gif image.
-*
-*   @param  $x  String containing the content to search and replace in.
-*   @result Returns the modified string.
