webadmin,userportal: Fix IE image size quirk

IE automatically adds "width" and "height" attributes, with
values taken from "src" image data, when an <img> element is
created via Image constructor function. For example:

  var img = new Image();
  img.src = "foo.png";
  // adds "width" and "height" automatically
  document.body.appendChild(img);

This causes render issues for images that use "src" attribute
for initial placeholder image and CSS styling for the actual
image. For example:

  <style>
    .fooImage {
      background: url("foo.png");
      width: 400px;
      height: 200px;
    }
  </style>

  <img src="clear.cache.gif" class="fooImage">

In IE, above <img> element would have "width" and "height"
attributes, with values from "clear.cache.gif" placeholder
image, added automatically:

  <img src="clear.cache.gif"
       width="1" height="1" class="fooStyle">

To fix this quirk, "width" and "height" attributes of such
images are set to value "auto":

  <img src="clear.cache.gif"
       width="auto" height="auto" class="fooStyle">
