Check whether you add the following handler under httpHandlers of web.config:
<add verb="GET" path="CrystalImageHandler.aspx" type="CrystalDecisions.Web.CrystalImageHandler, CrystalDecisions.Web,Version=13.0.2000.0, Culture=neutral, PublicKeyToken=692fbea5521e1304" />
Hope, it resolves the image issue.
