How do I make my image clickable?
After clicking on the 'upload image'-button you will be redirected to the page 'Billing details'.
Here, you will see the image you want to upload. Underneath your image, there is a URL-section.
Here, you can fill in your URL to make your image clickable.
Note: it works best if you directly copy and paste it from the address-bar from the website of your choice.
