Have been trying out the alternatives to PB and to date find PB and Imgur the easiest to use.
I have a paid PB account and find it very easy to use, also have free Flickr and Imgur accounts and some AFF gallery images.
Flickr is very difficult to navigate, not impressed at all.
AFF is greatly limited by file size, but otherwise easy to post pics to.
Here's a pic using Imgur, done in two clicks including change to file size, signed up and was using it within 2 minutes with ease, reckon its the best current alternative to PB.
