Embedding Facebook Photos
Problem
I know my users have some great photos in their Facebook Photos app and I’d really like to be able to embed them in my FBML.
Solution
Use the fb:photo
tag to embed photos from the Facebook Photos app. The
simplest form is:
<fb:photo pid="12345" />
Discussion
You’ll likely have found the pid of the photo you’re embedding through
the Facebook API’s photos.get()
method (see Chapter 9 for more information). If
you used FQL to find the photo, you’ll need to include the uid that you used in the query to find the
photo so that Facebook can make sure that user is allowed to view
it:
<fb:photo pid="12345" uid="12345" />
You can also specify a size
parameter, similar to the fb:profile-pic with the same allowable
sizes: thumb (t), small (s), normal (n), and square (q). See Worth a Thousand Words: Profile Pictures for a breakdown
of the different sizes. The final optional parameter is align, which can be either left or right:
<fb:photo pid="12345" size="t" align="right" />
The fb:photo tag actually
renders out a standard HTML img
tag, so if I embedded a photo of my dog, Findley, from my Photos album
of dog pictures, the FBML parser might ultimately insert this:
<img pid="2079254" uid="561415460" src="http://photos-g.ak. facebook.com/photos-ak-sf2p/v168/16/97/561415460/n561415460_2079254_773.jpg" />
If you need to style the inserted image using CSS, just treat it
like any other img tag.
