For this step you'll need to manipulate your photos, so they will look different from the original.
Oky, I just downloaded this photo from unsplash.com:

Please understand I am not trying to create a piece of art, just to help you make an idea about what you can do.
I took my cup of coffee I 'need' and now it is almost ready to use it in my post - asuming I really need it, this is only an example.. almost because it is not really ready until we pass step three ;)
I cropped and changed color and shadows, you can do much more according with your needs.
To obtain this, it may work any photo editor. But if you don't already have one, I can reccommend the Adobe Photoshop Express.

Now, if we do the same like in the upper example:
... we have now an 'original' product photo, which is almost ready to be inserted in our post - just not yet! After step 3...
