CastImage for Chrome is a free browser extension developed by Myappmarks. It falls under the category of Browsers and is classified as an Add-ons & Tools subcategory.

This extension allows users to easily share images on a Chromecast device. With CastImage, one or more people can cast images from their Chrome browsers to a shared CastImage session running on a Chromecast. There are multiple ways to cast images, including using a 'Cast Image...' context menu entry, taking a snapshot of the current tab, or uploading a local image file.

One of the notable features of CastImage is its experimental feature that allows users to cast a URL instead of just an image. This adds more versatility to the casting experience.
