Richard still uses Piscasa, and he backs up to iDrive. Are his pictures being backed up? Leo says the ones on the hard drive will be. But Picasaweb in the cloud no longer exists. It's now Google Photos. But it largely depends on what your backup options are. Check in the settings to make sure. But where are the photos? Leo says to look in your Picasa User Profile; it should be able to tell you. The Picasa Database is another location. There's also Google Photos. It's what Google wants you to use, even though there are not that many editing features to play with. A good alternative is ACDSee. But it isn't free. Snapseed is another. Irfanview. Dark Table. And Adobe's Photoshop Express. For Linux, Leo likes Raw Therapee.
