//lID: The id of your div, if it already exists it will not create anything
//lHTML: What you want to appear in the div
//lWidth: Default is 350. Set in px
//lHeight: Default is 50. Set in px
//lbVisible: Good for creating divs at page load and showing them later on. 
//      Sometimes animated gif might not animate on submitting pages as the image
//      isn't fully loaded when created at page submit.
//lTopOffset: Will place in the middle of the window if not passed in
//lLeftOffset: Will place in the middle of the window if not passes in
//lbShowLoadingIcon: Places a loading icon and your html in a table. You can acheive
//          the same effect by passing in the table an icon and your message as lHTML instead
//NOTE: If you want to add a div at page creation you need to place this function in bodycode as IE
//      will not allow you to dynamically append DOM objects while the DOM tree is being built.
//      Depending on your page setup, you may need to display the image AFTER you submit the page as IE
//      will freeze the animation if it is placed before the submit. ImportExportPictures.aspx has an example...
