Using this great plugin: github.com/blueimp/jQuery-File-Upload
Still needs error handling + delete picture.
Implementation of Uploadify in Rails3 + crop in Ajax.
clone it from github
install all dependencies with 'bundle install'
create the database with 'rake db:migrate'
fire it up with 'rails server'
Uploadify works well for multiple files handling.
in profiles/_form, set multi to true
in pictures controller, remove the test of previous picture existence in create
You'll see that all pictures are stored (I didn't bothered to display them for now)
I added 'ADD THIS' in the relevant files It's NOT a social app so user model is a fake as well as profile
