Using Google image search or another search engine, find a photo of a dragonfly or group of dragonflies. Find a photo of someone relaxing (or use a photo of you relaxing :-). Place the dragonfly(s) and the person in a "forest" setting.
Make the ending image size 800 pixels width (the height will vary for each). Save for web as a .jpg, and be sure to compress under 100KB.
