image-list --page-size <limit> returns all images

A curl request with limit=5 returned all 7 images available.

Investigating further, I learn with v1 api, setting page-size to 0 returns no images successfuly; setting page-size between 1 and 4 returns a 500 internal server error; and setting page-size to 5 to 7 returns all 7 images.

With v2 api, page-size any setting between 1 and 7, returns all 7 images. Setting page-size to 0 returns 0 images.

I realize now that I had two problems when I filed this bug.

1) I didn't fully understand the expected behaviour: http://docs.openstack.org/api/openstack-compute/2/content/Paginated_Collections-d1e664.html

2) I was testing with empty image placeholders (which caused the server errors) when I should have been testing with real images. Real images work as expected, outlined in the above linked document.
