How would you implement a fallback image in case the primary image fails to load?
- Setting the fallback image as a default value in the database.
- Using CSS background-image property.
- Using JavaScript to detect the error and replace the image.
- Using the alt attribute in the
tag.
The best method to implement a fallback image when the primary image fails to load is through JavaScript. You can use the onerror event of the ![]()
tag to detect the loading error and then replace the image's src attribute with the fallback image's path. The alt attribute is primarily for accessibility and doesn't serve as a fallback image. CSS background-image and database defaults are not direct methods for this specific scenario.
