Oracle Reports: Can I Use Multiple Image According to Query in One Report?

I want to use 4 different images according to where statement of my query. Is it possible in Oracle Reports?

I used formula column (in comment of @MichaelBroughton).

1. I added a formula column to my Data Model.
2. In property of column I choose Datatype = Character, Read from File = Yes and File Format = Image
3. This is PL/SQL Formula:

function CF_1Formula return Char is
begin
    null;
    if :column_a  = 1 then
      return 'c:\dir\image1.jpg';
    elsif :column_a  = 2 then 
      return 'c:\dir\image2.jpg';     
  end if; 
end;
