strcpy(tmpdirpath, fileimg); 

    strcpy(tmpdirpath, fileimg);
    if ((tmp = strrchr(tmpdirpath, '/')) != NULL) {
        tmp++;
        *tmp = '\0';
        strcpy(dirpath, tmpdirpath);

Hello, I believe these strcpy(3) calls can write beyond the bounds of the tmpdirpath and dirpath arrays.

Thanks
