Pop-Up JPEG

I don’t think so, when I use the code below:

imagea.onRelease = function() {
getURL(“javascript:Launch(floridaHammockZ.jpg)”);
};

I keep getting a runtime error:" floridaHammockZ not defined"

…and when I use the tutorial code:

imagea.onRelease = function() {
getURL(“javascript:Launch(‘http://www.kirupa.com/kirupa.htm’)”);
}

It works
