Answer 1

Since you haven't specified, I'll assume winforms.

So you've got 54 buttons and you've manually code up presumably 108 methods (54 for mouse enter & 54 for mouse leave)

What you could do is create an object to hold button->image info, and store it all in a dictionary. Key it by button Id. ie

public class ButtonImageInfo 
{  
     public string ButtonId {get;set;}
     public string MouseEnterImage {get;set;}
     public string MouseLeaveImage {get;set;}
}

// ...
public Dictionary<string, ButtonImageInfo> _dict = new ...
_dict.Add("Button1", new ButtonImageInfo ("Button1", "Image1Enter", "Image1Leave"));
///    ... etc...

That would allow you to code up one OnMouseEnter & one OnMouseLeave methods and apply them to every button.

You would then just grab the correct image based on the sender Id.

private void MouseLeaveEvent(object sender, EventArgs e)
  {
     Button b = sender as Button;
     if(b != null)
     { 
          string id = b.Id;
          //Do Something with _dict[id].MouseLeaveImage
     }
  }

  private void MouseEnterEvent(object sender, EventArgs e)
  {
     Button b = sender as Button;
     if(b != null)
     { 
          string id = b.Id;
          //Do Something with _dict[id].MouseEnterImage
     }
  }
