I have a little problem here. I managed to run it on my side using your images, however, when I change the img src to my own, it does not zoom. And I also noticed that there’s duplicate pictures with different namings in your pictures folder and I have done that too. Only thing is that I did not adjust the image size.
After trying out, I realised I do need to resize my pictures to at least 50% smaller. Your codes are amazing! Keep producing fabulous demos! Kudos!(:
