I have seen many posts about photo sharing sites.

You can have a look a new one called ComBoost : www.comboost.com

You just need to register for free, then you can easily share photos
with friends. The way it creates albums is really different from other
sites. You can actually organize them with drag & drops very easily.

Photos can be downloaded by your visitors, shared with e-cards...
Albums can be generated under pdf, and you also have a great slideshow
with effects. And if you have a website or a blog, you can actually
put your slideshow inside it very easily? then you update it directly
from ComBost.

Here is an example of gallery:
