Placemarks are saved views in Google Earth. The icon to place a Placemark looks like this:
1. Click on the Placemark button to put a Placemark down - the Placemark will drop in the center of the screen and save the view that you currently see.
2. Placemarks store information about the camera view -
Latitude
Longitude
Altitude
Heading
Range
Tilt
Elevation
You can see the Placemark information in the dialogue window. The latitude/longitude on the top is the location of the Placemark icon itself. The lat, long, altitude, heading, etc. below are the information for the camera view:
3. Updating the view - you can update the saved view of a Placemark by using 'Snapshot Current View', found in one of the two places below:
4. Additional preferences - you can adjust several settings to a Placemark, including:
Icon
Icon and label size
Icon and label Color
Altitude of icon
When placing a pin, a few things are important to remember:
If placing in an area with 3D buildings, the Placemark may be placed on the side or top of a building. You can force a pin to be on the ground by going to the 'Properties' ('Get info' on a Mac) and adjusting the Altitude tab to 'Clamped to Ground'. This won't effect the camera view, only where the Placemark is located.
You can move the Placemark icon around by grabbing onto it when the Placemark Dialogue box is open.
Adding a custom icon
Adding a custom icon is pretty simple, follow the instructions below:
1. Create your icon - be sure it's small enough to load quickly. PNG files are the best and no larger than about 60k
2. Go to the Properties of a Placemark - right click on the Placemark and go to 'Properties' on a PC, or 'Get Info' on a MAC

Once you choose a custom Icon from your hard drive, it will show up in the default icon list for easier finding in the future.
Notes:
When you are saving this Placemark to your hard drive, you must save it as a KMZ, not a KML, or the custom icon will be lost.
When you add a Placemark, it will default to the last one you chose
