This will show you step by step how to copy your images from one site to another. For this scenario, let us assume you have created a test site called TestSite. You have added images to that site, and now you would like to copy them over to your live site called LiveSite.
Since this process will download a file, it is better to do this on a PC.
Step 1 - Log in to TestSite
Log in to TestSite. From the side panel click on Tools then click on Export.
You could export your whole site, but for this example we want to export the images only. Click on the Media and select the date range for the images you want to export.
Click on the 'Download Export File' button. This will create an XML file and save it in your downloads folder on your PC.
