When adding or uploading images, most CMS platforms provide a field to enter the image title tags, and often by default this field gets pre-populated with the image file name or metadata if available. It’s always recommended to review and change the image title to better suit the image, if necessary.
If an image is added via HTML, then image titles can easily be added within the image code as follows:
<img src=”https://example.com/link-to-image.jpg” title=”The image title goes here” />
