If the user is logging in, presumably you are having the user hit a back end web-server and database and using something like Blaze to connect? Right?
I personally would not do this with CSS. I would map the company icons to the users in the DB, retrieve the proper company icon and then pass it down (or embed it in the app) when the user logs in. Then, I would just set the source of the icon to be what I passed down:
Add your image where you want it to go:
<s:Image id="emptyImage" x="locationx" y="locationy".../>
Then in your ActionScript, when the user logs in and you know what company the user belongs you could do this:
private function loginUserBlazeResponse(resultEvent:ResultEvent):void {
var bytes:ByteArray = ByteArray(resultEvent.target);
emptyImage.source = bytes;
addElement(img);
img.visible = false;
img.addEventListener(FlexEvent.UPDATE_COMPLETE, imageLoaded);
