Since I think that it is not possible to do it as I asked so I tried myself to do this with as short code as I can and then I got the following one That is also live on www.jsfiddle.net/JFx9g/18/
<style type="text/css">
.search_text {
position: relative;
}
.search_text:after {
content: "";
position: absolute;
top: -3px;
right: 7px;
width: 19px;
height: 19px;
background: url(http://i.imgur.com/BX2OXxc.png) -19px -2px no-repeat;
}
.search_text_input {
height: 24px;
width: 450px;
}
</style>
<span class="search_text">
<input class="search_text_input" name="q" type="text" value=""/>
</span>
