When you mention a problem like this, it is best to mention what device and/or app you are using. Because you list an iPad as your device, it can be inferred that you are using iBooks and the answer to your question of why is because it is a bug in iBooks.
Now you can code your large images to take 100% of the screen and not spill over.
If this is not an ePub you've made, then it's a poorly made ePub given that the image i way too large for most reading situations.
