Browsers do not always display images. There are a number of situations in which a browser might not display images, such as:

• Non-visual browsers (such as those used by people with visual impairments)
• The user chooses not to display images (saving bandwidth, privacy reasons)
• The image is invalid or an unsupported type
• Slow internet connection
