Image substitution for empty rich text Field

We had been searching for a way to display a 'no image available' image in our web-based catalog for some time. I found a method using simple JavaScript. This should work for any empty RT field displayed through a web browser. It seems that when an RT field is displayed in a form through a browser, domino puts in ecblank.gif when the field is empty as a placeholder in the html. This code reads that and substitutes in the new image in its place. In our case the image is image[0]. This would also work in a loop if there are many RT fields to replace.


Put the following at the bottom of your form. Substitute the name, width and height of your 'no image available' image.

<SCRIPT LANGUAGE=
JavaScript>
<!--
if(document.images[0].src.
indexOf('ecblank.gif')>0) {
window.document.images[0].src = 
'http://domain/icons/noboxshot.jpg';
window.document.images[0].height='168'
window.document.images[0].width='126'
}
//-->
</SCRIPT>
