 It appears useless.

 Entity tags are only unique to the resource. Two different images on
 different URIs having the same entity tag is meaningless. Per
 [http://www.w3.org/Protocols/rfc2616/rfc2616-sec3.html#sec3.11 RFC 2616,
 section 3.11]:

 > An entity tag MUST be unique across all versions of all entities
 associated with a particular resource. A given entity tag value MAY be
 used for entities obtained by requests on different URIs. The use of the
 same entity tag value in conjunction with entities obtained by requests on
 different URIs does not imply the equivalence of those entities.
