The interface is friendly and simple to use, while looking good. It is easy to upload multiple photos at once using what they call advanced uploaders.

The photos look good on the site and there are many ways of customizing your main page and albums - including various themes. There is also a nice couple of slideshows - one really simple and nice to embed one with a full-screen mode, which looks good as well.

Considering it as a photo sharing service, it does all I could wish for and adds some extras to make it more pleasant. Try it and see - there is a free 1 GB account available, so you may just as well decide yourself if you like it or not.
