There is a bug in Internet Explorer where it takes true-black
colours in JPG images and renders them to be transparent and thus shows the background
colour behind it when fading the image (in our case white). The dots disappear when the fading is complete.
The workaround is to go into Photoshop and adjust the levels to remove the true black areas from the
image – Image -> Adjustments -> Levels and slide the true black
slider 1 or 2 pixels to the right. Save your image again and the jpg
artifacts should be gone
