I have earlier done this. Sharing on Twitter and Facebook is much more difficult with Corona SDK now, then what it used to be 1-2 years ago.
For this post, I just need to ask if there is any help I can get for posting an image on twitter. I have tried my best by modifing the existing code, and using multipart/form_data request to HTTPS v1.1 statuses/update_with_media.json. Although the request is being formed correctly, I am not able to tweet media. I am able send a simple tweet though.
Can someone please help me or point me to the right direction?
