change shape of share images

I'm sorry for the delayed response.

You won't be able to get it exactly like the Pinterest button you have from another extension. We use Twitter and Facebook's Javascript libraries to render those buttons, and there are only a few options to choose from on how the buttons look. You should try the 'Layout' option in the JFBC Social Share settings to see if another option, like 'Box Count' works better for you.

You can see what each of the options look like using the Facebook Like Button Configuration tool .

I hope that helps,
Alex
