DataView dynamic content pictures

[okwei]

I'd like to use the DataView object for displaying a list of pictures, just like the example: http://extjs.com/deploy/dev/examples...data-view.html.

I will have a scrollable area for the pictures.
since my list of pictures are very long, in hundreds/thousands, I do not want to load up all the pictures when the page loads, so I'd like to dynamically load up the pictures when the users scroll to the corresponding position. I wonder if the dataview support this. If not, how do I tell if a picture is in the user's viewport in javascript?

thanks,
