Crystal Report Viewer not showing Images

Have you tried looking in your Web.config for the CrystalImageHandler (in httpHandlers section)? I had to add a line to get my embedded images to show up:

<add verb="GET" path="CrystalImageHandler.aspx" type="CrystalDecisions.Web.CrystalImageHandler, CrystalDecisions.Web, Version=10.5.3700.0, Culture=neutral, PublicKeyToken=692FBEA5521E1304"/>

If you are all alright on the Web.config section, and if you are on netFramework greater than 4.0 try this.

On the App_Start Folder, look for RouteConfig.cs and comment out the following line

 Settings.AutoRedirectMode= RedirectMode,Permanent;
