No installation or implementation issues for most of the sites I am using it with except for my own business site and my issue is just because I am using SSL on my site but Facebook passes the thumbnail links via http, not https. I emailed the developer and received a response very quickly with an attempt to work around the problem but in the end, it is simply the limitations of working with Facebook itself, not a problem with the Module. The developer was very helpful and even though the problem was because of Facebook, he tried to help find a solution.
All in all, I highly recommend this module to everyone. My plan is to actually use this module to implement photo galleries on some of my clients websites. Most photo galleries have issues with photo sizes when you are on a shared hosting server so I can have my clients simply use Facebook's powerful servers and photo processing system to upload to and store images and implement the module to display them on the websites very nicely.
This component is AWESOME. I found it this morning, put it on his site, and then called him and had him try it. He loves how easy it is.
Thanks and keep up the great work!!
