If you drag a file from a folder other than the one containing the current page, Composer automatically copies it into the same directory as the current HTML file. This means your links work correctly when you send the file to a Web server. The easiest and quickest way to get the right image onto your Web page is through Composer. The image is immediately inserted onto the page. Composer allows you to save entire Web pages, including text, graphics, and everything, on your computer to be viewed whenever you want.
Composer opens with the page in the window.
As from the Composer menu, then select where you want to save the page and click on Save. The entire page copies to your computer. Click on Choose File and select the saved file. Double-click on Open, and the page opens in the Composer window. Once you've inserted an image in the Web page you're working on in Composer, you can set some properties.
