Hello,
Your description was not explaining what you needed. I don't know whether you want an app(for iOS/android/PC) which should post status for one social media account or you have multiple accounts.
I'm afraid that if you want to automate the process, you can automate it to a very little extent, because APIs don't allow much freedom.
though through some image processing technique I can make it work, but it will require significantly more days in that case(and it is not safe :))
- Regards
