Can someone please help me?

Can anyone explain to me how to convert and combine this bit of code into an array that will function as buttons and load the images?

// - - - <Load ThumbNails> - - - \\
this.MC_thmb0.onRelease = function() {_level0.myMCL.loadClip("Images/Img0.png", imgContainer);};
this.MC_thmb1.onRelease = function() {_level0.myMCL.loadClip("Images/Img1.png", imgContainer);};
this.MC_thmb2.onRelease = function() {_level0.myMCL.loadClip("Images/Img2.png", imgContainer);};
this.MC_thmb3.onRelease = function() {_level0.myMCL.loadClip("Images/Img3.png", imgContainer);};
this.MC_thmb4.onRelease = function() {_level0.myMCL.loadClip("Images/Img4.png", imgContainer);};
 
 
function loadThmb() {
    _level0.myMCL.loadClip("Thumbs/Thmb0.jpg", this.MC_thmb0.thmbPic);
    _level0.myMCL.loadClip("Thumbs/Thmb1.jpg", this.MC_thmb1.thmbPic);
    _level0.myMCL.loadClip("Thumbs/Thmb2.jpg", this.MC_thmb2.thmbPic);
    _level0.myMCL.loadClip("Thumbs/Thmb3.jpg", this.MC_thmb3.thmbPic);
    _level0.myMCL.loadClip("Thumbs/Thmb4.jpg", this.MC_thmb4.thmbPic);
};
 
loadThmb()
