Comment 2 for bug 1443089

looks like glanceclient has an option for page size:
https://github.com/openstack/python-glanceclient/blob/master/glanceclient/v1/images.py#L206

page_size = kwargs.get('page_size', DEFAULT_PAGE_SIZE) where DEFAULT_PAGE_SIZE is 20.

I wonder how horizon and glance CLI handle this, or HP public cloud for that matter.
