Rohith have a look here http://community.elgg.org/pg/plugins/webgalli/read/492716/mothers-day-theme-for-elgg-171

This is what I did,in the header_contents.php found in the page elements (you will need to work with the image size...

<div id="page_container">
<div id="page_wrapper">

<div id="layout_header">
<div id="wrapper_header">
    <!-- display the page title -->
    <h1><a href="<?php echo $vars['url']; ?>"><img src="http://your.net/images/me.jpg" border="0"></a></h1>
</div><!-- /#wrapper_header -->
</div><!-- /#layout_header -->

Find the right view file and add a <div> </div> in the right place. 

Depends on which video plugin you're using.

thanq, i hav succesfully installed the izap_videos plugin, its working now

but while adding the videos with embed code, i would like to put a note(hint) above the  "add title" box.  can anyone help me please....

Rohith,

You do not have a similar interface as dashboard. You'll need to edit cuatom_index/views/default/canvas/layouts/new_index.php. I think custom_index has latest members and latest groups by default.All the best.

There are 2 files you need to edit:

custom_index/views/default/canvas/layouts/new_index.php
custom_index/index.php

Adding new things to the page is easy enough, just follow how other things are added to it and change the code to fit the objects you want displayed.

Good luck!
