    To turn on the preload image function for this component, you have to specify the component's attribute map with key "org.zkoss.zul.image.preload" to true. That is, for example, if in a zul file, you shall specify <custom-attributes> of the component like this:

     <image ...>
     <custom-attributes org.zkoss.zul.image.preload='true'/>
 </image>
    Or specify it onto the root component. For example, 
     <window ...>
     <custom-attributes org.zkoss.zul.image.preload="true"/>
     <image .../>
 </window>
    [Since 6.5.2]

    Preload image function is also configurable from zk.xml by setting library properties. For example, 

     <library-property/>
     <name>org.zkoss.zul.image.preload</name/>
     <value>true</value/>
 </library-property/>
