here’s what I need to do:

  • get number of images (imgs.length)
  • width of each image (here they are all the same width)
  • create left and right links
  • work out where we are currently
  • if click left or right, go onto previous or next image
  • create counter that shows which image i'm on
  • create visual counter, e.g. blobs with current blob being different colour
  • when click on blob, take you to that image
  • still looks a bit borked!
