## Description

Image Data is a powerful Chrome extension that reveals detailed information about images on any webpage, new tab, or even local files. On mouse over, it displays key details such as the image's resolution, scaled resolution, file name, file type, file size, alternative text, MIME type, source domain, total pixels, and modification date. Users can customize the display position with six options, including over, before, after the image, fixed positions, following the cursor, or tooltip format.

The extension offers keyboard shortcuts and a toolbar button for easy enablement or disablement. With full CSS customization, users can tailor how image data appears to fit their preferences. Image Data enhances productivity and convenience for developers, designers, and general web users who need quick access to image properties directly within the browser.
