Uploading photos

I need to upload photos to a web hosting site which is free amd allows the public to access the photos. There are several sites about I know, but any suggestions would be helpful. Below are the ones which I have so far shortlisted.

Imageshack.us

Flickr.com

Facebook is another but I have concerns regarding personal data issues on the site.

Thanks.

Rychard, you can try Photobucket.

I've been using it since 2004. Very reliable and easy to use.

Account storage is 500 MB bandwidth is 10 GB.

Another one is Picasa Web, which is under Google.

I used to use Picasa to host my photos for my blog. I used the service for 2 years +. Never had a problem with it. Very reliable.

Depending on what the photos are for/of. You could use Deviant Art.
But if its not artistically linked, i don't think its a good idea.

All the sugestions so far are pretty good.

Thanks Jay for the suggestions, currently looking to upload some photos of buildings and other subjects. On taking a look at them, Imageshack gave me unlimited storage but Flickr and Picasa gives better exposure. Looks like I will have to use more than one. Also thanks Genersis, all ideas are helpful.
