A JPG-LARGE file is an image from Twitter that stores the original size of the photo. The only difference between these files and regular ones is their large dimensions--they can be upwards of 50 MBs!
A user may download a picture online with Google Chrome if they‘re looking for something specific. However, there‘s no way to tell what kind of format this particular social media site uses before downloading anything onto your computer, as all images come packaged within JPEG format.
Still, if you cannot open JPG-large files on your computer, remove large from the extension part and open it as a JPG file.
