What is the differences between ALT Text (Alternative Text) & Title Text in a photo within a Blog?

 In a photo blog, ALT text and title text serve different purposes, though both are related to enhancing the accessibility and usability of images:

Aquí tienes una ilustración visual que compara el uso del texto ALT y el texto del título (title text) en un blog de fotos, destacando cómo se aplican en diferentes contextos. El ALT text se enfoca en la accesibilidad, mientras que el title text aparece como una ayuda contextual cuando pasas el cursor por encima.

1. ALT Text (Alternative Text):

   • Purpose: Describes the content of an image for users who cannot see it. This includes people using screen readers due to visual impairments or when an image fails to load.
   • Functionality: ALT text helps search engines understand the content of the image for SEO purposes and provides a textual replacement if the image can't be displayed.
   • Example: For an image of a chess board mid-game, the ALT text could be: "Chessboard with pieces positioned for a King's Gambit opening."
   • Usage: It should describe the essential content or purpose of the image in a concise, informative way.

2. Title Text:

   • Purpose: Provides additional information or a tooltip when the user hovers over the image. This text is not read by screen readers and does not serve as a substitute if the image fails to load.
   • Functionality: The title is often used to give more context or details about the image or link but isn't as critical for accessibility or SEO.
   • Example: For the same chess image, the title text might be: "Learn more about the King's Gambit opening strategy."
   • Usage: It is more of a supplementary detail or note that the user can choose to view by hovering over the image.

In short, ALT text is essential for accessibility and SEO, while title text offers additional context for users when they interact with the image.
