Looking for a tool that creates nice pinterest pin image

Looking for a tool (or npm package) that creates nice pinterest pin image given some text and image.
If someone knows something like that I'll be happy to hear about it.
If I can't find something like that - I'll just develop it myself

What I'm trying to do is give input of some photos and text and get output of hundreds of images that combine text+photo and randomize some of the stuff (colors, font, position).
