loadMovie jpgs won't work in browser but will in player?

For some reason i can’t get my loadMovie jpgs to show up in the browser. It works fine when not in a browser.

the movie itself is actually loaded into a scrolling pane, which is in a movie that gets loaded into the main movie. Here’s the script if that helps any:

function makeThumbnails() {
	var xl = xCoords.length;
	for (var i in photos) {
		var btn = this.createEmptyMovieClip("photo"+i, this.getNextHighestDepth());
		var btnHit = this.createEmptyMovieClip("btnHit"+i, this.getNextHighestDepth());
		btn._lockroot = true;
		btnHit.attachMovie("picholder", "picholder"+i, this.getNextHighestDepth());
		btnHIt._lockroot = true;
		btnHit._alpha = 0;
		btnHit.loadFile = photos*.file;
		btnHit.w = photos*.w;
		btnHit.h = photos*.h;
		btnHit.onRelease = function() {
			launchPopUp(this.loadFile, this.w, this.h);
		btn._x = xCoords[i%xl];
		btn._y = 20+(Math.floor(i/xl)*120);
		btnHit._x = xCoords[i%xl];
		btnHit._y = 20+(Math.floor(i/xl)*120);
