Hi guys.. There's a nice free app to share your photos with your friends. This is the app I mostly use for share my photos with my friend's phone. It's so easy to use and quite simple. And it automatically organize your photos inside of your device.

There's the description on playstore:

Easily connect any two mobile phones and send photos!

Want to send a photo on your phone or in your cloud to someone right next to you? They don’t have the same type of phone as you? Picture Beam makes it easy to send that photo from your phone to any other type of phone, and forget about using email, phone numbers, or Bluetooth. Simply:

1) Select the photo or photos you want to send that are stored on your phone
2) Photo Beam creates a unique tag on your phone
3) Anybody with any type of mobile device, using any barcode reader, can scan the tag on your phone and instantly get your photos.

**Use the barcode reader installed on Picture Beam for the best experience.

**USE PICTURE BEAM WITH NFC**
If the sending and receiving devices have NFC, and both devices have Picture Beam installed, you can send photos using NFC:
1) Select the photo or photos you want to send that are stored on your phone
2) Photo Beam creates a unique tag on your phone
3) Hold the two devices up to each other, back to back.
4) Press your finger and hold it on the middle of the screen of the device sending the photos.
5) The receiving device will receive the photos automatically
