What is the best way to load and unload images to help save memory.
Is there a global way to do this?
how about set the Image's source to "" for unload the image
You can also use a Loader to dynamically load and unload large items.
You may also want to use the 'cache' property on image: http://doc.qt.nokia.com/4.7-snapshot/qml-image.html#cache-prop . Try setting that to false.
