If there is a number field eg. rating, reduction, price, age,.. then it is possible to change the number into an image. It looks more attractive then just the number.
You can do this either:
- with computed field
- rewriting a view field
- with a reference field
We will discuss the last option. An example.. I choose rating as a number.
It shows as a picture.
First we make a content type for the images.. Just an image field..
We make the nodes for every option. The title will be our options in the refernece field.
Every time we use the corresponding image.
then we implement in another content type the field
Referencing the image content type.
Make in the content typ that in the view mode, you render the entity.
