How to update the photo that comes up when I post link on facebook?

Hello, 

When i post my link i see the logo of the template showing up as the pic attached to the link. How can I update that

I believe that you are referring the image that shows in the preview when attempting to post it on Facebook, correct? I cloned the form and the same image showed up:

I could not find it anywhere in the form, I tried clearing the forms cache, but it still show there.

Let me forward this to our back-end team to see how this can be updated. You will be notified via this thread.
