Reporting Services Image Problem Export Excel, Copy Paste ?

I have a server report which made by ssrs 2005, I am using vs 2005 to build an aspx page and call this report which already uses dynamic query. I use parameters and send these to reportviewer with setparameter method. I dont use DataBind and Refresh method. SetParameter is enough to generate Report. When report generates everything is fine. But when i export this report to excel the pictures in this report get smaller to fit in cell height. I used rendering extensions but its same.


try

{

ReportViewer1.ServerReport.SetParameters(paramList);

//ReportViewer1.ServerReport.Refresh();

//ReportViewer1.DataBind();



}

catch(Exception exc)

{

Response.Write(exc.ToString());

}



And i used copy contents of reportviewer and paste it to excel file. There is interesting case here. If this is the first time that i run the report and copy and paste. No image is seen in excel workseet but other report elements is fine. But if i click on refresh button on reportviewer toolbar and report regenerates, i try to copy and paste and it works fine, and if i dont close ie window copy and paste progress works good and i dont need to click on refresh button on each report to copy and paste?

This is so interesting subject, i tried lots of things for example i tried to use databind and ServerReport.Refresh methods maybe it acts like clicking on refresh button but this wasnt the same only difference is it took more time to generate the report.

Any help?
