How do I edit the template?
You can edit the HTML code for the page within your File Manager, or any text editor.
You would need to download the images to your computer if you want to work on them. From your Favorites you can click "Download the HTML file with images and CSS file" or "Download blank images to go with this template" and this will give you an archive of the files.
After you have the Template files extracted into a folder, you can use a graphic editing program to change the images.
