Until Domino provides this internally, you can use JavaScript to do this. Create a $$ViewTemplate and add this code so it runs after the view page is loaded:
<SCRIPT LANGUAGE=JavaScript> var i, nullcount, expand, collapse;
expand = new Image(); expand.src = '/icons/expview.gif'; // place URL to your image for expand (but don't name it expand.gif) collapse = new Image(); collapse.src = '/icons/colview.gif'; // place URL to your image for collapse (but don't name it collapse.gif)
nullcount = 1; // initialize nullcount to non-zero so it enters the while loop.
// while loop tests if all the images are loaded by the browser while (nullcount) { // Reset nullcount which counts number of images remaining to download. nullcount = 0; // document.images is collection of all images (<IMG> tags) on the document // it has length attribute representing the image count. for (i = 0; i < document.images.length; i++) { if (document.images[i].src == null) // src is property storing image url nullcount++; else { if (document.images[i].src.indexOf('expand.gif') > 0) // checks expand document.images[i].src = expand.src; else if (document.images[i].src.indexOf('collapse.gif') > 0) // checks collapse document.images[i].src = collapse.src; } } } </SCRIPT>
