I setup the image source virtual image list 16x16 and inserted the image index in to the html code. i.e. however no image shows when I run the program. Note that the image list is populated at run time because the .ico files are 32bit and that is the only way to load and keep the good look and different sizes for the virtual image list. Is that the problem (is the image embedded in to the html rather than referenced when shown) ?
