You can't make Yahoo Mail show compiled PHP code, but you can make the user run it.
You see, when a web browser calls a webpage, he recieves the web page. Then, for every media element: pictures, backgrounds, objects that aren't on the page, the user has to request too.
Images capitlize on this idea: when someone opens up an image and sees an external image, he is, inadvertantly, requesting for info from that site that the image is on. The site then, is allowed to modify their cookies, do stuff, blah blah. That's why most email clients let you block external images.
