I am interested in this assertion.  Suppose, instead, the ALT text
read "Papilio xuthus : photographed resting on leaf of Phelloderldron amurensis;
image taken using Zuiko macro lens at 4cm on Olympus OM4-Ti, f/16, 0,5 seconds,
ISO 100 (ring flash); photograph taken 05:17 on Monday 18-Jun-2006, Kuril Island".
Would that also be (in your opinion) "useless as ALT text", and if so, can you
suggest what suitable ALT text might be ?
