Dynamic Image Unload

So, thanks to the forums here, I’ve learned how to dynamically load an image on a particular frame in one of my scenes. Now, when I click and link to another page, the pic stays there. Is there a command or code I can write in so that when I exit that scene, or better yet, frame, the image unloads???

Here’s the code that’s calling the image in…

BioImages._x = 300, BioImages._y = 45;
