Image title and alt text both serve important purposes for web accessibility and search engine optimization (SEO), but they differ in their usage and significance.
title attribute of an image is typically displayed as a tooltip when a user hovers over the image. It provides additional information about the image and can enhance user experience, but it doesn't have significant impact on SEO. The image title might not be read by screen readers (which assist visually impaired users in navigating the internet) depending on their settings.

alt attribute, or alt text, describes the content of the image, providing a textual alternative for those who cannot view the image.

You should aim to include meaningful alt text for all images, describing the image content accurately for both SEO purposes and accessibility. Image titles can be used as supplemental information or left out if not necessary.
