Being different even with free themes
Free design themes come with default background; changing it will probably be one of your first steps.
Background image is an auxiliary file; in order to change your background, simply replace background.jpeg with your image.
You may need to clean browser cache in order for changes to make effect.
It makes no sense to use large (width > 900 pixel) image file for the background.
We suggest using free images (e.g., from Pixabay) or self-made photos to avoid copyright infringement.
