How can I rearrange buttons and delete product images on my website?

Hi In need helop I want to put these 3 button quantity add to cart and buy it now below after product details. Can someone help me.

And also how can I delete this photo in the product page. this is the image that I uploaded as the photo of the product but I don’t want it in the product page automatically appearing.

@JeanACNOC , do this to remove the image in 20 seconds:

  1. In your Shopify Admin go to: online store > themes > actions > edit code
  2. Find Asset > theme.css and paste this at the bottom of the file:
#shopify-section-product-template .primary-media-types  {
    display: none;
}

To place the variants below the description would be a bit more complex.

Kind regards,
Diego
