Insert/Remove photos depending up on ref. cell value changing

Hello,
I designed a Student Profile in excel using LOOKUP function. In this profile, near the Student Name title I created one drop down list of students. If I select a student, then Roll No, Admission No, Date of Admission, Date of Birth, Mother's Name, Father's Name, Residential Address etc are shown downwards one by one in the respective cell automatically. I also need to insert his/her passport size photo in the prescribed cell, according to the Admission Number cell value. All the students' photos are put in one folder, each one named as Admission Number. First I select one student name from the drop down list displayed in his/her profile page, then printout will be taken. After taking that page printout, I will select another student. That time the photo of the previous student should be removed and the photo of the newly selected student should be displayed. If you know how it works (using any function/macro) please help me.
