I'll update the component to use images instead of icons. I'll use placeholder images for this example, but you can replace them with your actual images later.

I've made the following changes to the component:

1. Replaced the icon components with <img> tags.
2. Used the placeholder image URL format /placeholder.svg?height=64&width=64 for each image.
3. Set the image container size to 16x16 (64px) to match the placeholder image size.
4. Added appropriate alt text for each image for accessibility.
5. Centered the images, titles, and descriptions within each promo box for a more balanced look.

The rest of the component structure remains the same, maintaining the border layout and responsive design. You can replace the placeholder image URLs with your actual image URLs when you have them available.

I'll update the Three Column Promo component to ensure that the text and images in the promos are left-aligned.

These changes will left-align the images and text in each promo section. The images will be aligned to the left edge of their container, and the text will follow suit. I've also added a bit of top margin to the headings to maintain good spacing between the image and the text.

Remember to apply these changes to all three promo sections in the component. The overall structure and responsiveness of the component remain unchanged.
