title: Using OpenFileDialog w/ a relative path as initialDirectory
body: <p>I'd like to give the appropriate value to Initial directory, so it would open the folder (called "Images") which I created in my project.
  I must use a relative path, so my program works not depending on the computer I work .
  But the problem is I don't know how to access this folder...</p>
  
  <p>Does anyone know how to solve this problem?</p>
