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.

Expected Error Behavior

Browsers show partial image with grey band at bottom. Pillow raises 'image file is truncated' error. Some viewers display nothing.

How to Fix

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