saving images to picture box

I don't have much knowledge on phone-to-computer file transfer via c# and I think it strictly depends on phone brand (it could be near to impossible for iPhone, for example). But after that stage, you can show a photo in a picture box as http://stackoverflow.com/questions/11487901/c-sharp-change-pictureboxs-image
and save that file to your database as binary data or string64 representation, depending on your approach.
