Well, there is always going to be some tradeoffs involved. Maybe the image is 'overflow: hidden' until you hover over it. I'm thinking layout shouldn't be altered for cases like below: 

<img src='spacer.gif' alt='I was put here by an author who's never heard of margin:1px' width=1 height=1>

<img src='g.gif' alt='tracking beacon for xyz.com' width=1 height=1>
