Keep in mind that as of right now, Google Photos does NOT support the BBCcode for posting individual photos in a bulletin-board post, which is what you'll need if you want to post pics from your site here on VAF. I used Picasaweb for years, but now that Google is dumping it, I am moving to Flickr. Flickr has an app that backs up your phone photos, and it's really easy to make an online photo album with them. (Just like Picasa used to be.) My Picasa log is just one big album, but now I've started breaking my build down into a collection with several albums inside it for different sections of the airplane.
I used to write a blog, but got tired of it, so now I just upload my pictures, type a quick caption of what I did, and POOF. The date is there, too. The only thing I wish I had done differently is keep track of actual hours spent building. I started to do this, but lost track a few years ago. It's like counting trees whizzing by as you drive a country road... after a while it's all just a happy blur.
The reason I chose Flickr is that it has a nice app and is supported by Snapfish.com, which has a neat service where you can create and print a picture book. A Panther buddy turned his build log into a coffee table book, and it's awesome!
