Twitter Image is a free Chrome add-on developed by Wondoo Kang (a.k.a. Azyu) that allows users to easily obtain the original size image from the Twitter and TweetDeck websites. With this add-on, users can right-click on an image on Twitter or TweetDeck and easily download the image in its original size.

The add-on leverages the Chrome Web Browser API to enable this functionality. By simply right-clicking on the image, users can access the option to download the original size image. This makes it convenient for users who want to save high-resolution images from Twitter or TweetDeck.

It is important to note that the add-on does not allow users to change the download folder location, as this is not allowed by the Chrome Web Browser API.

Overall, Twitter Image is a useful add-on for Chrome users who frequently use Twitter or TweetDeck and want to easily download original size images from these platforms.
