Hello. Thanks for you fast response. 
In response to your questions, the tile is always bigger that image.
If i re-assign the dataProvider to the tilelist,

      tilelist.dataProvider = element;

the image don´t appear. The image is loaded via HTTP, then the source 
of image is like, http://webserver/images/thumbnail1.jpg. Can be a 
problem?

re-assign the dataProvider after you've adjusted the slider, do the 
images appear?
