Folks ... 

sorry forgot the breaks in the switch ... 

it should be

int lazy_check(image_desc_t *im){
    FILE *fd = NULL;
    int size = 1;
    struct stat  gifstat;  
    
    if (im->lazy == 0) return 0; /* no lazy option */
    if (stat(im->graphfile,&gifstat) != 0)
      return 0; /* can't stat */
    /* one pixel in the existing graph is more then what we would
       change here ... */
    if (time(NULL) - gifstat.st_mtime > 
        (im->end - im->start) / im->xsize)  
      return 0;
    if ((fd = fopen(im->graphfile,"rb")) == NULL)
      return 0; /* the file does not exist */
    switch (im->imgformat) {
    case IF_GIF:
        size = GifSize(fd,&(im->xgif),&(im->ygif));
        break;
    case IF_PNG:
        size = PngSize(fd,&(im->xgif),&(im->ygif));
        break;
    }
    fclose(fd);
    return size;
}
cheers
tobi
