Add-on I want this custom add-on...

[OverHere]

Basically, I want to use https://dev.twitter.com/cards/types/summary-large-image in my threads so that I can get the first pic in a thread to appear in my website's Twitter account like what you see at https://twitter.com/Earth_Pics

So, in each thread where only 1 pic is posted that pic should automatically be forwarded to my website's Twitter account; where there are several pics posted in a thread, only the first pic in the thread should be posted on the Twitter account...

Can any one here make such an add-on?

Thank you...
