It's possible that this issue is related to how Internet Explorer loads data needed from CSS classes. Might I suggest an alternate approach: instead of using the loading animation contained within a CSS class, just put the . Gif in a visible img tag straight into the HTML.
Then, when onSuccess or another method is called, you can just run.
As already commented on, it looks like it doesn't have anything to do with the GIF image itself, especially not one at 20x20 pixels.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
