Your listing details page is not displaying a photo when the page initially loads. The photo will display if you click on another tab, such as Map Property, then click back on the Photos. This issue generally applies to any site using version 2 listing format.
This is caused by the window.onload script being used multiple times on a page. Some customizations of the template may have used this feature. It needs to be updated to addLoadEvent(functionname); This can be done in the ZSERIES Studi Design Center. This fix will not work for version 1 websites, the site must be version 2.
This is an advanced issue and should be submitted to our support department.
