Use the Layer feature in Google only when necessary. Each layer added to Google Earth will add rendering time each time the map is moved and redrawn.
Especially taxing, yet very cool, is the use of the 3D layer.
Often the layers can be extremely useful teaching resource, such as the geographic options.
Using the Digital Global coverage layer, will assist students in viewing when the latest image of each location was last taken.

Have students design a storyboard prior to beginning their project. The storyboard should contain the locations they are going to select, and the images, sounds or video, they will be adding to the location.
Keep all images in a single folder, keep image names as short as possible.
Make sure images are resized to less than 3” for a better fit and reduce the resolution. 72 dpi is perfect for web viewing.
You can add an image to a placemark. Google earth supports the following: JPG,BMP,GIF, TIFF, TGA, and PNG formats.
The most common issue when inserting and image overlay is the size of the image. It is important to keep this in mind when designing your project or edit graphics in a graphics editor prior to adding to the project. Larger images can also be memory intensive. Images less than 3” in size and saved at 72dpi is prefect.
All objects added into the placemark, must be added using hypertext markup language (HTML). I have prepared a cheat sheet to assist you with the basics.
In the preplanning we saved the images in a folder, and gave them a short name. To insert the image in the placemark you will need to know the location path to the image. To get this path, you will right click on the image and go to properties. Highlight this path, right click and choose copy.
You will need to start the line by keying <img src=“ paste path add

If you create a video and save it to Google Video’s it can be Geotagged for use on Google Earth.
Upload the video to Google Video. Once the video has been uploaded, click on the Embed Video link, a drop down box with coding will appear. Copy this coding and paste it into your properties area of the place mark in Google Earth. This will embed the video into the place mark.
