Thankyou Message

Hi

I would like to add a picture... and to say few more things

Hello,

To do that you can either :
- Edit the value of the "THANK_YOU_FOR_PURCHASE" translation key via "Hikashop->System->Configuration->Languages"
Or
- Directly edit the code of the "After_end" file of the "Checkout" view of your front-end template via "Hikashop->Display->Views"
