In the Site Content tree on the left, click on the images folder.
Look for a red plus sign in the topmost header area of the page, and click on Add Content.
Inside the Add Content menu, select Upload a File.
Drag and drop an image from somewhere on your computer into the browser window, or choose one from your computer. The File Name will automatically populate with the file name previously given to the image. There are minimal photo editing options available that you can use to resize or crop your image.
Click Preview Draft. After previewing the draft, click Submit to save the image to the CMS.
The image has been successfully saved to the CMS. You should now Publish your image.
Select Publish.
If your site has been assigned a live or test URL, all publishing destinations have been set for you and you can click Publish from the Publish File menu to confirm.
If your site has not been assigned a live or test URL, you will not be able to publish your image and will see the following message. The image will still be available to build pages.
Images uploaded to the CMS can be inserted into a page via a WYSIWYG editor by clicking on the Insert/edit Image button regardless of publish status.
