editing django website

1) When you go to payment portal and try to go back it glitches

2) adding product variants is done in a very rubbish way, need to fix that and make it easier to add variants and display them

3) product pics cant be zoomed, client must be able to zoom

4) there is a glitch when adding a price it displays as something else before checkout ( this one i need to check today as client just reported it)
5) one image needs to be fitted to thr login page it isnt fitted correctly
