My app won't draw a fifth image

Question

I am working in Android Studio and trying to draw a few images. However, the app stops running after I put the fifth image. When I take away the fifth image the program works just fine. I do not have any java code set to do anything so this is the only place where the problem could be. Here is the XML:

<?xml version="1.0" encoding="utf-8"?>

    tools:layout_editor_absoluteY="402dp" />

</android.support.constraint.ConstraintLayout>

How do I fix this issue?
