How about something like this?
<img src="javascript:generateImage(1e6*Math.random()>>0);" alt=""/>
function generateImage(seed){
/* use the seed to write generate an XBM image here */
return image;
}
That code could be made entirely side effect free, but still useful.
From mathematic standpoint:
By its definition Math.random() function is not side effect free
in ECMAScript. It uses static variable for generation of pseudo-number
sequences.
