What is Image Data?

"Image Data" is a versatile Firefox add-on that provides an all-inclusive detail of any image on a webpage, new tab, or even local files. It displays the image's resolution, scaled resolution, file name, type, size, alt text, mime type, domain, pixel total, and modification date. By placing the cursor over an image, the user gets to see all these details promptly. It also includes the option of six position settings and comes with customizable elements via CSS. The add-on can be easily managed through keyboard shortcuts and a toolbar button.
