In the code change the image acquisition: NDrawingView1.ImageAcquisitionMode = Nevron.UI.WebForm.Controls.ClientSideImageAcquisitionMode.TempFile; 2. Create a directory called NevronTemp in the root folder of your website - for example (C:\Temp\WebSite2\NevronTemp if the web site is located at C:\Temp\WebSite2\). 3. Give this folder read, write, modify permissions to the ASP.NET account. Hope this helps - let me know if the problem persists. Best regards, Bob
