Profile-Mode: Generate a resize image

if the image is present in `assets` directory.
- Resizing the image will reduce the size of a large image.
- Should improve image load time.
- Usage:
  - Add the image under assets directory.
  - Provide path in `profileMode.imageUrl`.
  - if image is located as `assets/images/image.png` mention `profileMode.imageUrl: images/image.png`.
