I use SlideshowFX for several years now and its the ONE add-on to manage private albums on google+ (or former picasa). Help is fast. I always got 24hr responses, even when the developer was on holiday.
Using this module, I could get rid of the standard widget layout Twitpic offers me and style the pictures just like I want on my website.
I ran into a problem with the beautiful JS Highslide function, which allows your visitors to stay on your website, watching Twitpic pictures in a popup and the developer responded within hours with two solutions, of which one worked!
