  <apex:sectionHeader title="Upload photo of {!obj.name}"/>   
    <apex:form id="theForm" >
    <apex:pagemessages />
        <br/>
        <apex:outputText ><b>1. Select the photo</b></apex:outputText><br/><br/> &nbsp; &nbsp; &nbsp;
        <apex:outputText > Click the <b>"Choose File" </b>to find the photo.</apex:outputText><br/><br/>&nbsp; &nbsp; &nbsp;
        <apex:inputFile title="Upload Photo" contentType="{!objAttach.ContentType}" value="{!objAttach.body}" fileName="{!objAttach.name}" id="file"></apex:inputFile>

    public Attachment objAttach{  get {
                                        if(objAttach== null)
                                          objAttach= new Attachment();
                                        return objAttach;
                                     }
                                   set;
                                 }

    Public Contact obj{get;set;}

     public PhotoUploadController(ApexPages.StandardController controller){
