My basic Login Form

The line: bodyStyle: 'padding:5px;background-image:url(graphic/graph.jpg);' does what you are asking.

function openLogonWindow() {
 var txt_User = new Ext.form.TextField({
      name: 'Username',
      fieldLabel: 'User name',
      width: 175,
      allowBlank: false
 });
 
 var txt_Password = new Ext.form.TextField({
      name: 'Password',
      fieldLabel: 'Password',
      inputType: 'password',
      width: 175,
      allowBlank: false
 });
 
 var btn_Logon = new Ext.Button({
      text: 'Logon',
      handler: function() {
           form.getForm().submit({
                waitMsg: 'Validating credentials...',
                success: function() {
                     //Do What Ever
                },
                failure: function() {
                     //Do What Ever
                }
           });
         }
 });
 
 var btn_Cancel = new Ext.Button({
      text: 'Cancel',
      disabled: false,
      handler: function() {
      window.close();
 });
 
 var form = new Ext.form.FormPanel({
      baseCls: 'x-plain',
      labelWidth: 300,
      labelAlign: 'top',
      title: 'Enter your Credentials',
      items: [txt_User, txt_Password],
      buttons: [btn_Logon, btn_Cancel],
      keys: [{ key: [10, 13], fn: function() {
           btn_Logon.focus();
           btn_Logon.fireEvent("click", btn_Logon);}
      }]
 });
 
 var window = new Ext.Window({
      width: 200,
      height: 190,
      layout: 'fit',
      plain: false,
      resizable: false,
      modal: true,
      draggable: false,
      closable: true,
      bodyStyle: 'padding:5px;background-image:url(graphic/graph.jpg);',
      items: form
 });
 
 window.on('show', function() { txt_User.focus(); }, null, { delay: 1000 });
 window.show();
}
