There is no straightforward way to do this at the moment. The only way to force a reload would be to modify the image url to ensure a new image is requested from the image provider - for example, by appending some unique number that then is ignored by the image provider.

This is something that should be fixed. Could you file a bug at http://bugreports.qt.nokia.com to track this issue?
