>Thanks for the response. What I'm actually trying to do is change dimensions of the image control when a postback occurs - depending on the dimensions of the jpb file I want to display. I see on the html view of the aspx page where I can manually change this - but I'm looking to programmatically change it depending on the user selection ...

Well, it's always good to force the dimensions to be part of the HTML. I talked about that in my December article in Considerations when building Web applications. Without those dimensions, the page will jump at load time.

I'll keep searching on this. In the meantime, maybe someone will be helping to provide more info.
