pset4 recover - my implementation recovers 50 jpegs but check50 rejects

Question

I am having trouble with recover from pset4 - when I run it, it creates 50 images, apparently correctly formatted (000.jpg-049.jpg). However, check50 rejects it:

:) recover.c exists.
:) recover.c compiles.
:) handles lack of forensic image
:( recovers 000.jpg correctly
    000.jpg not found
:( recovers middle images correctly
    001.jpg not found
:( recovers 049.jpg correctly
    049.jpg not found

Here is my implementation:

/**
 * recover.c
 *
 * Computer Science 50
 * Problem Set 4
 *
 * Recovers JPEGs from a forensic image.
 */
#include <stdio.h>
#include <stdlib.h>
#include <stdint.h>
#include <string.h>

....
            sprintf(str, "%.3d.jpeg", t);
....

Prepare for a painful self-headslap. ;-)

File names are important. The code created 50 files with the extension .jpeg. The spec said to create files using the extension .jpg, without the "e". Guess what's happening. ;-)
