MIX09 is the Microsoft event of the year for all things web, so if you don't know what it is you should head over to VisitMIX and find out.
If you do know, you probably want to promote it... and just displaying the same old image for every visitor is so old fashioned, so I turned to my handy 4 lines of javascript to spice things up a little...
1: <script type="text/javascript">
2: var v1= Math.round(Math.random() * 6) + 1;
3: document.write('<br><a href="http://2009.VisitMix.com"><img src="http://blog.offbeatmammal.com/samples/MIX09/MIX09_BlogBling_' +v1 + '.jpg" border="0" alt="Visit MIX09"></a>');
4: </script>
or... even easier is to just insert this one line of Javascript into your page and as I find new bling I can update it automatically
<script type="text/javascript" src="http://blog.offbeatmammal.com/samples/mix09/mix09bling.js"></script>
if you define two variables in your javascript before you call the random blog bing script then you can over-ride the width and height - just like this
<script type="text/javascript">
var bling_width=120;
var bling_height=160;
</script>
<script type="text/javascript" src="http://blog.offbeatmammal.com/samples/mix09/mix09bling.js"></script>
and you can see the results here (just refresh the page to see it change)
