Adding add to cart button

I’ve setup my products and have given a link below each that directs them to buy now page that is setup at “Plimus”. I need to add add to cart button besides each product and then proceed like people normally. I don’t know he process. How to do it?

Normally I would copy and paste an image from anywhere then just hyper-link it to where ever you want it to go, If Not Upload to server and repeat process…

Yes! I would agree with this. This is what also my friend told me… So I tried to look for “Add To Cart” images.
