Looking for good photoblog website

Hi all,

i'm looking for a good photoblog website. My "requirements" are :

- should provide high-quality view of the pictures (ex : wide picture size, option for full screen view of pictures, good picture compression that doesn't affect the quality)

- can be (but not necessarily) offered with a website

- should allow (if possible) full size upload AND download of pictures (so we're talking about 15 MB pics for JPEG)

- should allow (if possible) uploads of NEF files

- Lightroom plugin integration

Even if i would prefer a free tool, i'm open to a reasonnable yearly fee...I looked at a couple options but i'm not 100% conviced by any...My latest try, Zenfolio, looks promising...Any suggestions which could match my expectations ?

Thanks in advance !
