Online gallery HQ download (mobileme style)

Please help, with the introduction of Aperture 3.1 ive probably had my last "drink" with steve. In November I have to renew - but to what. My clients, most of them on PC are highly impressed of the ease of mobileme to view and download high res and low res images. For me it has always been really slow process but as it goes through Aperture I have learned to live with it.

However the latest iteration really killed it for me and im jumping ship. So please if anyone know of a really good online gallery type style that looks professional and where the client can download a Full res image and low res image while looking though a gallery that is nice - please please let me know.
Im not looking at Flicker, facebook etc styles. Needs to be good and stylish.

cheers!!!

Thanks a lot for some of teh PMs i have received! Howver im not looking for a place to sell and people can search my images. All my images that goes up are already sold, its just a way for a client to choose what he / she wants to download. ie it has to be a lot of "galleries " with password per gallery.

If you were asking LR specific, TTG could fit: http://lr.theturningga​te.net/

That looks promising, it means I will host it my self as well.

Looked solid, but it wont export hi res for you so you have to do that seperately and then upload them to a specified folder, the less things I have to do - the less things will go wrong...

Still looking
