Unfortunately, it is not possible to have 3 different images, at least not without some customization. You could upload a 255px thumbnail and set your product.tpl to show it full-size and then have X-Cart resize the thumbnail on your products display to 90px. The problem with php resizing is that the thumbnails will look kind of crappy.
