A JPG_LARGE file is a JPEG image with “.jpg:large” in its URL. Twitter appends this when the image is large. Google Chrome then saves it with the custom “JPG_LARGE” extension. These are normal JPEGs. To open, rename to “.jpg”.
File extension jpg_large labels JPEG files as very large. But they are standard JPEGs. Any JPEG software can open them. Chrome creates JPG_LARGEs when downloading Twitter pictures. You can rename to .jpg.
The JPG-LARGE extension comes from a Google Chrome bug. When saving large Twitter JPEGs, Chrome adds “.jpg:large” to the URL. So it saves as “.jpg_large” instead of “.jpg”. Still, JPG-LARGEs are regular JPEGs. To open, just change the extension to “.jpg”.
JPG-LARGE files are JPEG images flagged as big by Twitter. Chrome then gives them a custom extension on download. But they are regular JPEGs. Rename to “.jpg” to open normally.
The .jpg_large extension was created by a bug. In Google Chrome, large JPEGs downloaded from Twitter get “.jpg:large” added to their URL. So Chrome saves them as .jpg_large instead of .jpg. Though named differently, JPG-LARGE files are normal JPEGs. Simply rename to .jpg to open.
