Regarding the image ID thing, it is caused by the current image cache. I started working on [JCLOUDS-512](https://issues.apache.org/jira/browse/JCLOUDS-512) to fix that, but it is a bit complex as there are providers, such as AWS, that cache images differently. I can't give an ETA, but I hope we'll have that fixed soon. With the actual (partial) fix, you should be able to get the new image using the TemplateBuilder and providing the imageId. But the listImages and ImageExtension fixes are still a WIP. Meanwhile there is the (not good) workaround to close and reopen the context again.
