    We have a asp.net project where I put a RadCaptcha on an ASP.NET page (using VS2013).

    We have the latest version of ASP.NET tools installed.

    When trying to run the application where the web is located, the RadCaptcha image is not showing up.

    The web.config has the following items:

    Under System.Web

    <add path="Telerik.Web.UI.WebResource.axd" type="Telerik.Web.UI.WebResource" verb="*" validate="false"/>

    Under System.WebServer

    <remove name="Telerik_Web_UI_WebResource_axd"/>
    <add name="Telerik_Web_UI_WebResource_axd" path="Telerik.Web.UI.WebResource.axd" type="Telerik.Web.UI.WebResource" verb="*" preCondition="integratedMode"/>

    Hello Aric,

    The issue you are experiencing looks very similar to the problem, described in this forum thread.
    Could you please try to configure RadCaptcha to store the captcha image in the session as it is described in the following help article:
