How to add social media button (eg FB, Twitter) to each single product page?

Hi victorlai,

Firstly you would need to create an sharethis account here http://sharethis.com/createaccount then follow below steps

1) You open the template file of app\design\frontend\default\jm_lingerietemplate\c atalog\product\view.phtml to add a html mockup like this

HTML Code:

 <div class="social"> 
					<span class='st_facebook' displayText='Facebook'></span>
					<span class='st_linkedin' displayText='LinkedIn'></span>
					<span class='st_twitter' displayText='Tweet'></span>
					<span class='st_sharethis' displayText='ShareThis'></span>
					<span class='st_email' displayText='Email'></span>
				</div>

Then open the file app\design\frontend\default\jm_lingerietemplate\p age\html\head.phtml to add this

HTML Code:

 <script type="text/javascript">var switchTo5x=true;</script>
<script type="text/javascript" src="http://w.sharethis.com/button/buttons.js"></script>
<script type="text/javascript">stLight.options({publisher: "your Publisher ID", doNotHash: true, doNotCopy: true, hashAddressBar: false});</script>

Notice here the your Publisher ID should be replaced by your actual Publisher ID that you get after create an account.
Hope this helps !
