Changing Sparks images

[rubylyn]

Simple question I'm sure,but I just can't figure it out:o
How can I use this image http://rubylynsplace.homestead.com/files/flower.gif in this script, and maybe have it different colors?:


div id="sparks"
<div id="sDiv0"
style="position:absolute; visibility: hidden;"><font face="arial black" color="red">.</font></div>
<div id="sDiv1" style="position:absolute; visibility: hidden;"><font face="arial black" color="yellow">.</font></div>
<div id="sDiv2" style="position:absolute; visibility: hidden;"><font face="arial black" color="blue">.</font></div>
<div id="sDiv3" style="position:absolute; visibility: hidden;"><font face="arial black" color="red">.</font></div>
<div id="sDiv4" style="position:absolute; visibility: hidden;"><font face="arial black" color="orange">.</font></div>
<div id="sDiv5" style="position:absolute; visibility: hidden;"><font face="arial black" color="white">.</font></div>
<div id="sDiv6" style="position:absolute; visibility: hidden;"><font face="arial black" color="green">.</font></div>
<div id="sDiv7" style="position:absolute; visibility: hidden;"><font face="arial black" color="skyblue">.</font></div>
<div id="sDiv8" style="position:absolute; visibility: hidden;"><font face="arial black" color="yellow">.</font></div>
<div id="sDiv9" style="position:absolute; visibility: hidden;"><font face="arial black" color="white
