Users can easily access this information for images found on webpages, in new tabs, or even local files. The add-on supports customizable display settings, allowing users to position the information in several ways, such as over, before, or after the image, making it a flexible choice for different viewing preferences.

In addition to its robust functionality, Image Data offers keyboard shortcuts and a toolbar button for quick activation. The display of image data can be fully customized using CSS, enabling users to tailor the appearance to their liking. With its permission to access data across all websites, Image Data seamlessly reads and presents image information, ensuring an efficient and informative experience for graphic and design tasks.
