Questions Regarding Images in Custom Inspector/Editor

Question

I'm trying to make it so one can edit the texture from the editor right of the name string and left of the Remove Character button, I can get an image to display their if I add it in the Element however I'd like to base.OnInspector and hide those variables later.

I'd like it so in Image 1 you can click the image to change it to a different texture, the way you can in Image 2. If you click them you'll understand what I'm talking about.

         c = GetComponent<CharacterList>();
     }
 
     public CharacterList GetCharacterList()
     {   
         return c;       
     }
 
     [CustomEditor(typeof(CutsceneManager))]

         void OnEnable()
         {
             cM = (CutsceneManager)target;
             c = cM.GetCharacterList();
         }
 
         public override void OnInspectorGUI()
         {
             if (GUILayout.Button("Create Character"))
             {
                 AddCharacter();
             }
 
             for(int i = 0; i < c.characters.Count; i++)
             {
                 GUILayout.BeginHorizontal();

Got it working.
