With Google 'encouraging' all Picasa users to move over to Google+, I needed a WordPress solution to keep using Picasa that was more stable than the Picasa site (the semi-private link to my main albums page, which my extended family used to see what we were up to, was not showing all the albums. Also, I need another social network like I need a hole in my head).
I'm a novice @ WordPress- I know just enough to be dangerous! When I hit a few snags during the install, the developer worked with me to help iron them out. I'd recommend the pro version for some great extra features as well. This is a solid, straightforward plugin!
