Its worked in Firefox 3.0.18

Here, i received image id using both h:form and h:graphicImage tag id's

JSF code is :

<h:form id="fileViewerForm">


<h:panelGrid columns="2">
<h:commandButton value="Print" onclick="printImage();"/><br>
<rich:panel id="imageViewerPanel">
<h:graphicImage id="imageViewer" url="sampleImage.png" value="sampleImage.png" width="200" height="200" />
</rich:panel>
</h:panelGrid>


</h:form>


The Java script is :


function printImage()
{
var iamgeId = document.getElementById('fileViewerForm:imageViewer');
var imagObject = new Image();
imagObject = iamgeId;
var originalImage = '<img id="imageViewer" src="'+imagObject.src+'" height="'+imagObject.height+'" width="'+imagObject.width+'" />';


popup =  window.open('','popup','toolbar=no,menubar=no,width=200,height=150');
popup.document.open();
popup.document.write("<html><head></head><body onload='print()'>");
popup.document.write(originalImage);
popup.document.write("</body></html>");
popup.document.close();
}
