<input type="file" name="PIC" id="PIC" onfocus="if(this.value!=='')showimg.innerHTML='<img src='+this.value+'  onload='javascript:DrawImage(this);'>';"/> <div id="showimg"></div> <br />

<input type="file" name="PIC" id="PIC" onfocus="if(this.value!==''){showimg.innerHTML='<img src='+this.value+' onload=DrawImage(this) />';}" />
