Showing multiple layers using one checkbox {Scanned} {Scanned}

[Siki Zoltan]

Hi,

You should add relative or absolut URL in src tag. e.g
<img src="/path_from_DocumentRoot/legend.gif" width="159" height="77" 
border="0">
or 
<img src="http://server_name_or_ip/path_from_DocumentRoot/legend.gif" 
width="159" height="77" border="0">
or
<img src="relativ_path_from_cgi-bin/legend.gif" 
width="159" height="77" border="0">
(relativ path probably starts ../)

For example if your legend.gif is in the images directory of the 
DocumentRoot directory of your server then
<img src="/images/legend.gif" width="159" height="77" border="0">
or
<img src="http://192.168.1.130/images/legend.gif" width="159" height="77" 
border="0">
or
<img src="../images/legend.gif" width="159" height="77" border="0">

Bye
Zoltan
