HTML Images

Visual media elements integrate photographs, graphics, and illustrations into web documents through img tags configured with source paths, alternative descriptions, and dimensional properties.

Images embed via <img> elements, forming crucial components of compelling web experiences. Strategic implementation balances visual impact with accessibility requirements and page performance optimization.

Understanding Visual Elements

Image elements inject visual media into HTML documents, presenting photographs, diagrams, iconography, and supplementary graphics. The <img> tag facilitates this integration.

Strategic Image Advantages

  • Amplify aesthetic quality driving visitor engagement
  • Communicate concepts rapidly through visual channels
  • Reinforce brand identity via consistent imagery
  • Enable accessible consumption when correctly implemented
  • Boost search rankings through optimization practices

Image Element Fundamentals

The void <img> tag requires src attributes indicating image file locations.
