Problem with the images of the sex member

Hi folks, I have a little problem here... I am using Dolphin 6.0.5. In Profile Fields I create the sex of male, female, couple, couple (m) and couple (w), but all the images are set as Visitors! How I can fix the image to show the right image depending the sex of the member? Somebody can help me with this, please!!! Thanks a lot for all!
