Image Metadata Viewer is a free Chrome add-on developed by Jorticus. It falls under the category of Browsers and specifically the subcategory of Add-ons & Tools. This program allows users to easily view EXIF or PNG metadata of most images.

With Image Metadata Viewer, accessing image data is a breeze. Simply right-click on an image and select "View Image Metadata" to see a convenient popup displaying all available image data. This feature is especially useful for photographers or anyone who wants to delve into the technical details of an image.

The program also offers a specialized layout for Stable Diffusion users, organizing prompt and model parameter data in a readable and copyable manner. This makes tuning parameters for images much more convenient, especially when working with Automatic1111 and related UIs (note that ComfyUI nodes are not supported yet).

One notable aspect of Image Metadata Viewer is its commitment to user experience. The developer has ensured that the extension is free from ads and other monetization methods. This sets it apart from other extensions that often bombard users with broken features or excessive advertisements.

Although the current version does not support Adobe XMP tags, the developer has promised to add support in the future. In fact, the developer encourages users to share their ideas for new features or report any bugs they encounter via email.

Image Metadata Viewer is a valuable tool for anyone who needs quick and easy access to EXIF or PNG metadata of images. With its user-friendly interface and commitment to improvement, this Chrome add-on is definitely worth a try.
