Images can improve understanding, break up long sections, and make blog content easier to share. They can also slow a page, create accessibility problems, or look generic when selected without a clear purpose.

Every Image Should Have a Job

A useful image may demonstrate a process, compare options, show an example, explain data, or establish the subject of the article.

Decorative images should still support the tone rather than distract from the content.

Image Selection Checklist

  • Relevance: Relevance to the article's topic, section, audience, and intended business tone.
  • Licensing: Clear licensing or ownership allowing the image to be published and promoted.
  • Dimensions: Appropriate dimensions and composition for the website's featured-image layout.
  • Readability: Readable charts, screenshots, or text at both desktop and mobile sizes.
  • Consistency: Visual consistency with the company's colors, photography, and illustration style.

Optimize Before Publishing

  1. Resize the image to the maximum dimensions needed by the layout.
  2. Compress the file and choose an efficient format without damaging clarity.
  3. Use a descriptive file name and concise alt text explaining meaningful content.
  4. Preview the page on multiple screen sizes and check loading performance.

Common Mistake to Avoid

Avoid adding keywords to alt text that do not describe the image. Alt text primarily supports people who cannot see the visual. Decorative images may not require descriptive alt text, depending on implementation.

Use Visuals to Support the Reading Experience

Thoughtful image management improves both presentation and usability. A consistent workflow also helps teams avoid oversized files, unclear licensing, and last-minute formatting issues.
