Apparently not. This is the output of glance image-show:

Looking at the code in
https://github.com/openstack/nova/blob/master/nova/api/ec2/ec2utils.py#L70and
https://github.com/openstack/nova/blob/master/nova/api/ec2/ec2utils.py#L126it
seems that the conversion is simply done by getting an id of type
integer (not uuid-like string) and then converting it to hex form and
appending it to the string 'ami-'

Question is: where this id comes from and is there any way to show it in
the horizon web interface?

.a.
