Problem of Segmentation fault in Pset4 (Recover) of CS50

Question

I’m with a problem in my code, because Every time I Try to run it I get "Segmentation fault", but I can’t find the error. The code is:

#include <stdio.h>
#include <stdlib.h>

int main(int argc, char *argv[])
{
//Checking if there is only one command-line argument
    if (argc != 2)
    {
        printf("Usage: ./recover image\n");
        return 1;
    }

    //Opening the forensic image and checking if it could be opened
    FILE *input = fopen(argv[1], "r");
    if (input == NULL)
    {
        printf("Could not open input\n");
        return 1;
    }

    FILE *image = NULL;
    unsigned char buffer[512];
    int found = 0;
    int nameCount = 0;
    char imageName[8];

    while (fread(buffer, 512, 1, input) == 1)
    {
        if (buffer[0] == 0xff && buffer[1] == 0xd8 && buffer[2] == 0xff && buffer[4] >= 0xe0 && buffer[4] <= 0xef)
        {
            if (found == 1)
            {
                fclose(image);
            }
        
            sprintf(imageName, "%03d.jpg", nameCount);
            image = fopen(imageName, "w");
            if (image == NULL)
            {
                return 2;
            }
            fwrite(&buffer, 512, 1, image);
            nameCount++;
            found = 1;
        }
        else
        {
            if (found == 1)
            {
                fwrite(&buffer, 512, 1, image);
            }
        }
    }

    fclose(image);
    fclose(input);
}

Could someone help me to figure out what to do, Please?
