Description

The image contribution guidelines in the README.md are currently written in a single line. To improve readability, they should be formatted as a bulleted list.

Current Code

The line currently reads:
⭐ Make your image accessible by including helpful alt text that describes the image. ⭐ Ensure your file name is descriptive. A file name of img01.png isn't helpful. ⭐ Use hyphens instead of underscores in file names to keep our naming conventions consistent.

Suggested Change

Please update this section to use proper markdown formatting, for example:

⭐ **Make your image accessible** by including helpful alt text that describes the image.
⭐ **Ensure your file name is descriptive.** A file name of `img01.png` isn't helpful.
⭐ **Use hyphens in file names** (e.g., `my-image.png`) instead of underscores (`my_image.png`) to keep our naming conventions consistent.
