I believe you have to specify the jpg path. Image1.ImageUrl = Server.MapPath(~/slid.jpg); (ensure that the slid.jpg is successfully created in the web application folder)

String filePath; filePath = Server.MapPath( /Some/Virtual/Path/on/your/WebSite ); filePath += \{0} ; String fileName = slid.jpg ; // This should be dynamic too so you can have more that one picture of a slide String fileNameAndPath = String .Format(filePath slid.jpg ); pptPresentation.Slides[ 1 ].Export(fileNameAndPath jpg  320  240 ); Image1.ImageUrl = String .Format( /Some/Virtual/Path/on/your/WebSite/{0}  fileName);
