[jQuery] jqModal position loading gif

[Bradley]

$("#modal").jqm({
   ajax:'@href',
   ajaxText: '<img alt="Loadinganimation" id="loadingModal" src="/
images/loading.gif />'
})

I'm trying to get the loading gif to be centered in the window, but
it's always in the top right corner of where the modal window shows
up.  here's the CSS:

.jqmWindow, .jqmID1, .jqmID2{
    display: none;
    position: fixed;
    top: 17%;
    left: 50%;
    margin-left:-350px;
    z-index:3001;
}

.jqmWindow #loadingModal{
        position:relative;
        left:50%;
        top:200px;
}

the above css doesn't seem to affect the image at all.  Can anyone
tell me if there's a specific class applied to this image and how I
might manipulate where it's placed while the content is being loaded
via ajax?
