Custom field image

Is it possible to have an image in a custom field?

The custom label I have is:

Type zip code above, then select ![+](<a href= "Link: https://dorothy.com/Icons_Leo/plus-button-green.png")https://dorothy.com/Icons_Leo/plus-button-green.png"; width=“18”> to the left of your zip code

The image does not show.

What type of component are you using this custom label for?

Field editor > Field properties > Search Field > Search name
