Customizing your application by replacing an image
Some customization tasks require you to replace one image with another, using the same filename.
The image filenames are hardcoded into the gbc-project-dir/src/index.html file. To update the image, you need to replace that named file. For example, the favicon image is always called gbc_logo.ico; if you want a new favicon image, you must overwrite the current gbc_logo.ico file.
