Thnx for the links... tried some, but still with no success... I now have the
following:
public class Image extends MovieClip
{
private var _thumbLoader:Loader;
private var _largeLoader:Loader;
private var _thumb:Bitmap;
private var _large:Bitmap;
public function loadThumb() :void
{
_thumbLoader = new Loader();
_thumbLoader.contentLoaderInfo.addEventListener(Event.COMPLETE,
thumbLoaded, false, 0, true);
_thumbLoader.contentLoaderInfo.addEventListener(IOErrorEvent.IO_ERROR,
errorOccured, false, 0, true);
_thumbLoader.load(new URLRequest(_tu));
}
private function thumbLoaded( e :Event ) :void
{
_thumb = Bitmap(e.currentTarget.content);
_thumb.smoothing = true;
addChild(_thumb);
_thumbLoader.contentLoaderInfo.removeEventListener(Event.COMPLETE,
thumbLoaded);
_thumbLoader.contentLoaderInfo.removeEventListener(IOErrorEvent.IO_ERROR,
errorOccured);
_thumbLoader = null;
dispatchEvent(new Event(Image.IMG_LOADED));
}
public function loadLarge() :void
{
_largeLoader = new Loader();
_largeLoader.contentLoaderInfo.addEventListener(Event.COMPLETE,
largeLoaded, false, 0, true);
_largeLoader.contentLoaderInfo.addEventListener(IOErrorEvent.IO_ERROR,
errorOccured, false, 0, true);
_largeLoader.load(new URLRequest(_lu));
}
private function largeLoaded( e :Event ) :void
{
_large = e.currentTarget.content;
_large.smoothing = true;
addChild(_large);
_largeLoader.contentLoaderInfo.removeEventListener(Event.COMPLETE,
largeLoaded);
_largeLoader.contentLoaderInfo.removeEventListener(IOErrorEvent.IO_ERROR,
errorOccured);
//_largeLoader.content.dispose();
_largeLoader = null;
dispatchEvent(new Event(Image.IMG_LOADED));
}
public function disposeLarge() :void
{
if (_large)
{
removeChild(_large);
_large.bitmapData.dispose();
_large = null;
}
}
public function dispose() :void
{
disposeLarge();
removeChild(_thumb);
_thumb.bitmapData.dispose();
_thumb = null
}
}
Anyone some tips? The large bitmap stays in memory...

Hi,
I think if you use it locally, you still have to "dispose" of it:
http://www.bartclaessens.com/tag/memory-management/
http://labs.bigspaceship.com/2007/02/28/flash-performance-tips-part-ii/
http://www.gskinner.com/blog/archives/2006/06/as3_resource_ma.html
Search for "dispose" in some of these - also, one of the comments in
Grant's article mentions testing in the IDE vs testing in the browser
gives different results for loaded images.
