Hi
In answer to your question there is an easy way to add the pop up that you are after. But first go to
http://www.skype.com/share/buttons/ to get your code, then depending on you preferred location just copy & paste it in.
Mine goes something like this, in the skin1/customer/home.tpl:
<
td class="VertMenuRightColumn">
{if $active_modules.SnS_connector && $config.SnS_connector.sns_display_button eq 'Y' && $sns_collector_path_url ne ''}
{include file="modules/SnS_connector/button.tpl"}
{/if}
<!--
Skype 'My status' button
http://www.skype.com/go/skypebuttons
-->
<script type="text/javascript" src=">
<a href="skype:what ever your skype name is?call"><img src="http://mystatus.skype.com/balloon/dlp%2Eskype" style="border: none;" width="150" height="60" alt="My status" /></a>
</p>
{if $active_modules.Feature_Comparison ne "" && $comparison_products ne ''}
Hope this helps and if the user does not have Skype they get a download pop up.
