I am trying to do something like this.
This was done on shopify but I do not know if they just uploaded an image or if they used gallery for this.
My focus is so that it is not compressed when it shows up on mobile.
Thank you in advance!
Sorry you are facing this issue, it would be my pleasure to help you.
