I'm not sure you understand what I am after.
I don't want to do a pick myself (apart from obvious rejects out of focus, to black). I want to be able to give the whole image set to the client so they can choose the images they want and then give them to me back and I can then somehow import their picks into lightroom so I can see them and then edit the images they have choosen. Does that make sense?
What Jitendra is suggesting is to use Lightroom Web for this. In your catalogue you add the photos to a collection, sync it to Lr Mobile, make the collection public, share its URL with the client. The client then needs an Adobe account (so set one up such as email@example.com and give them the details). They then "favourite" images, can enter comments, and you automatically see those entries in your catalogue. You can sort the collection to find which photos they choose.
