I’ve created a ImagePicker class that lets you pick images from device gallery and add them as CCSprite’s to your scene! At the moment it only supports Android and iOS(iPad), but I think I will have some more time in two weeks so I will add support for other platforms.
It can be found here : https://github.com/Losiowaty/ImagePicker
Hope that someone will find it usefull.
If you have any questions/suggestions or you found a bug please write here.
