It may be because the parent path is not enabled on the IIS server.

Solution:
In IIS
Properties> Home directory> Configuration> options. Check "enable parent path. Confirm refresh.
If the server provider does not enable the parent path for 'security considerations, it is recommended to write the absolute path when the path points, that is, the complete address such as "http://www.freeyule.com/template/default/images/logo_n.png"

After iis6.0 is installed, the parent path is disabled by default.
