Adding images in HTML: sources, alternative text, and title attributes

Images make web pages more dynamic, attractive, and visual. They serve to illustrate ideas, break up blocks of text, and improve user understanding. However, adding an image in HTML involves more than just displaying a file: the correct use of the src source, the alt alternative text, and the title attribute ensures accessibility, better SEO, and a superior user experience.

img tag and basic concepts

The tag for images in HTML is img. It is a self-contained tag and at minimum needs the src attribute for the file path and alt to describe the image. Examples of use as text: <img src=images/logo.png alt=Site_logo> and <img src=https://example.com/banner.jpg alt=Promotional_banner>. If the path is incorrect or the image does not load, the browser will display the alternative text.

How to set the source with src

Different types of paths can be used depending on where the image is located: relative paths for resources in the project, for example <img src=images/logo.png alt=Site_logo>, or absolute paths for external images, for example <img src=https://example.com/image.jpg alt=External_image>. Keeping clear paths and descriptive file names helps with maintenance and SEO.

Importance of the alt attribute

The alt alternative text is key for several reasons: accessibility, since screen readers use it to describe the image to users with visual impairments; SEO, because search engines use that text to understand visual content; and as a fallback when the image does not load. To write a good alt, you must be specific and concise, describing what the image shows. If the image is purely decorative, the alt should be left empty, meaning no alternative text is provided, so that screen readers skip it. Examples: <img src=team-photo.jpg alt=Our_sales_team_at_the_2025_retreat> and for a decorative image use an empty alt in the HTML or indicate in the code that it carries no alternative text.

Title attribute for additional information

The title attribute provides complementary information that is usually shown as a tooltip when hovering on desktop. Do not replace alt with title; title is optional and not always accessible from screen readers or mobile devices. Textual example: <img src=award.png alt=First_place_trophy title=Web_Design_Award_2025_Winner>. Use title only for brief and complementary data.

Complete example

An example that combines src, alt, and title could be represented in text as follows: <img src=artwork.jpg alt=Colorful_abstract_painting_by_Jane_Doe title=Spring_Harmony_2025_Jane_Doe>. With this, screen readers will read the description, search engines will receive context to index the image, and desktop users will see an additional tooltip when hovering.

Best practices

Always include alt unless the image is decorative. Use descriptive file names like paris-eiffel-tower.jpg instead of IMG1234.jpg. Compress images to reduce loading time. Avoid using images for textual content, except for logos; if essential, include the text in alt. Test the experience with screen readers to ensure accessibility.
