My client needs to put html (just links really) into image descriptions, so I've changed

printImageDesc(true);

to

echo htmlspecialchars_decode(getDesc());

However it isn't recognising the getDesc() function? There's something obvious that I'm missing here, but not sure what it is!

getImageDesc( ) perhaps?

Holy crap that works! Thanks heaps

Just to note: getDesc() is a class method and needs to be used with the global object of the current image like $_zp_current_image->getDesc(). That is indeed the same as getImageDesc().
