Very nice, may i suggest that you make it like so...
put that in the image...
onclick="document.elements['desc'].innerHTML=',$varfordesc,'"[code] (change $varfordesc to what u use for desc...)
on the end add this...
[code]<div name="desc">Click image to view description.</div>
this code might or might not work... i threw it together on the back of my head... what it does is makes the "Click image to view description" change to the desc... nifty no? =) [/code][/code]
