Please help if you can.

So I am fairly new to the whole Photoshop thing and need help urgently. I don't know if this comm will be able to help me or not but I am going to try.

I have the following image that I need to clean up: take out all the white (except for the heart that needs to be there), and make the background transparent not black. And it needs to be 1561 x 958 pixels.

If anyone can help me that would be awesome, it is a project for the shelter I work for.

Thank you in advance!
