In the left navigation of My EarthCam, click on "MyCam Page Designer." A sub-navigation will show up. Click on "Page Layout" or click here.

Here you can choose your camera image size by selecting the appropriate radio button. Next, select the radio button of the page layout that you prefer. You can also chose to include a "counter", which will track the number of people who have viewed your MyCam page.

Click the save button and you're done!
