One way is to go to Site Files and upload an image there inside the public folder. Once it's uploaded, click on the file name, you should be taken to the image in a new tab. You can then copy the url of that image from the location bar of your browser, and use that url in the form that pops up when you click the 'insert image' button in the page editor.
Trying to modify the site pages, I cannot understand where I have to upload images before I can use in this editor: I tryed to upload them into public and private files, or into my own files, but never I have them disposable in editing the home pages.
Thank you in advance for help!
