Two Methods for displaying automatically generated images on the ASP. NET page

Method 1: Save the automatically generated image to a location on the site, then you can set the SCR of the image control to the image URL in page_load on the page (the code for this method references the http://www.cnblogs.com/ahuang1118/archive/2005/05/27/163614.html)
Method 2: Set the SCR of the image control in webform1 to another genpicture URL that automatically generates images. See demousing system;
