Glance image ids (eg b3db0d80-bdea-45c3-aefe-9f7d0e94e1d7) are globally
unique.
Image names are not unique. This is by design, and I don't think it's
something we want to change.
If I remember correctly, you can provide either a *name* or an *id* to
the "openstack client".
The difference is that
* a name will work if you are lucky and it is unique
whereas
* an id will always work
For this reason, things that need to work reliably should work with ids rather
than names.
