Best photo sharing site?

[runningfool]

Can anyone recommend a good free photo sharing site that allows big images and with minimal advertising?

Of course I realise that you don't get owt for nowt but I'm sure some free sites are better than others.

I use Google Picasa,

If you go google-mad as I seem to have then you can get email, blog, documents all with one login and password.

I use Fotolia for stock images. Although not free you can upload your own artwork and get credits when/if someone buys yours. Quality images/artwork though and cost nowt to have a looky look.
