feat: Add image assets and attribution data

This commit introduces a new, modular system for managing image assets.

- Wrote the credits.js file to serve as a single source of truth for all image attributions.
- Replaced existing placeholder images with new, properly licensed assets.
- Created `_m-thumbs` and `_s-thumbs` directories with resized thumbnail versions of all original images.
