Truncated JPEG — Incomplete Image Stream
A JPEG file that was cut short, missing its End of Image (EOI) marker (FF D9) and potentially scan data.
Why It Fails
JPEG files must end with the EOI marker (0xFF 0xD9). A truncated file causes decoders to reach unexpected end-of-file while reading the compressed data stream.

How to Fix
Re-download the file. Use jpeginfo to check integrity. Set ImageFile.LOAD_TRUNCATED_IMAGES = True in Pillow for partial recovery.
