The rollover effect, which changes an image when you hover your mouse over it, uses Event Attributes to create the effect. As event attributes are able to execute javascript, their use is disabled unless specifically enabled in an Editor Profile. Once they are enabled, the Rollover tab will be visible in the Image Manager.

As event attributes are able to execute javascript, these should only be enabled in profiles assigned to trusted users.

To enable Event Attributes

  1. From the JCE Control Panel, click on the Editor Profiles button, then click on a profile to edit, eg: "Default"
  2. Click on the Editor Parameters tab, then on the Advanced tab.
  3. Set the Allow Event Attributes option to Yes. The Allow Event Attributes option will not be visible but will automatically be enabled if the Allow Javascript option is enabled.
