Show Image Notification If Post Under May 2012

[v123shine]

I have a site for buy and sell product. I want all user know if the post more than six month.

Can someone help me to create a simple plugin to display image notification if first post more than six month or less than"May 2012".

Yep, create a plugin using postbit_display_complete as the hook and drop this inif ($post['postid']==$this->thread['firstpostid'])
{
if(strtotime($post['postdate'])<strtotime('-180 days')){
$post['message']= $post['message']."<br /><img src='images/misc/MyGif.gif' border='0' />";
}
}
