Comment 1 for bug 1697728

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.
