The photo editor that Google made. The newest version can detect who's face is in the picture. With the newest version you can also
tag pictures with key
words, and you can sort pictures by where you took them. It is very easy to upload, edit, and share you're pictures. You can also take pictures directly on it, so you don't have to upload them. It's doesn't have as many tools as the more
high-tech editors such as
GIMP, but it is easier to use. Much better then picnik, and it is free to download.
