No, you can create a Text or Selectbox field.
The image is based on the field content, so the format is
<img src="http://yoursite/{content}.png">
Example, you have Selectbox field:

Then go to Videobox -> Settings -> Custom fields -> Fields in images -> In top -> select the field that you created. Use HTML in format to show image
