I added the facebook share button within an email body (.htm). The purpose of the button is to share the photo a user received in his email. When the button is clicked, a new tab opens with the "Write a message" area to share on facebook.
The problem is that once "Share Link" button is clicked nothing happens - no confirmation, no redirect, BUT the link is actually posted on Facebook (so the end user would not know the message has been shared unless they check their Facebook while all confused). Here is the code for the button:

```
<a title="Share this photo" 
href="http://www.facebook.com/sharer.php?
    s=100
&p[url]=%PHOTO_LINK%.jpg (dynamically populated link)
&p[title]=Check out my pic!"
target="_blank">
<img src="someplace.png" 
alt="Share on Facebook" height="50" width="50" />
</a>

```

I have tried using meta tags (title/description/url and the main namespace tag), but they are not picked up when shared (title/description is a bunch of random characters). Is this behaviour normal for share buttons of this sort, is it a bug or am I doing something wrong?

Thanks in advance
