There is now in 3.2
It will take a little extra effort instead of just the tag, but if you add the following, you'll get a text button for Login With Facebook.
<input type="button" value="Login With Facebook" onclick="javascript:jfbc.login.login_custom();" />
If you have a different image you'd like to use, you can also do:
<a onclick="javascript:jfbc.login.login_custom();"><img src="http..yourimage.png" /></a>
We'll be adding tags for the above in a future version, but hopefully, the above isn't too bad to get you started now.
Good luck!
