1. Copy the following code link and paste it into the block where you plan to set the RSS feed. For instance, if you are setting your RSS feed through twitterfeed.com, it would look like the image below.
2. Then go to the Facebook page and click on a photo from that page. Go to the url link at the top and copy the set of numbers right before (.&type=).
For example, you would highlight and copy the numbers I have highlighted below from the Facebook url:
3. Now go back to your RSS feed block that you had copied earlier. (In my case it would be the Twitterfeed block.) Paste these numbers after the (=) at the end of the RSS feed you had pasted earlier.
Now you have the entire RSS feed. Test it and make sure it will parse correctly and you should be set to go.
Note: Facebook is constantly changing things, so as of the date of this posting, this works. It may become obsolete once Facebook updates their site again.
