Nearly all websites use images for various purposes. Images might be used for banners, navigational buttons and various other ways to engage visitors to your site. Most users online are able to understand what an image is just by looking at it. However not all users can interpret exactly what an image is they could fit into the following categories.
- Blind users that utilize screen readers to understand web content.
- Users that disable images on their browser.(Often in emerging markets where internet speeds are slow)
- Users with slow internet that cannot download images.
- Users of standard browsers with text-only mode.
- Search engine crawlers that cannot interpret the graphic content (Google uses this information with its image search)
HTML allows an alt attribute to descript an image in readable text format. This helps search engine robots and people who cannot interpret the image. Below is an example of the image alt attribute.
