High resolution images to be added onto my shopify store

Hi,
I am an artist who has a website https://www.makethepiece.com/ and I want to add my work to the website to have the high res images on there with a click-through to each image of the work and to be able to zoom into the work to see the image up close and the details of them. I would like to be able to manage this myself after being set up with the initial images so I can add and take away work off the website in the future. I currently have the images on there under the title https://www.makethepiece.com/pages/current-work (current work) but I am unhappy with how they look on there as the images are not good enough and you are unable to zoom in. I need also the details of the size of the work to accompany the image. I can send the images of the work over to you if needed that I want to be added to the website.

Thanks
