You can be sure that BLOB will work properly ( as long as your read()/
write() calls do fail :) )

I will answer with an example that should clear things up.

printf("<img src=shoot_gif?pict_id=%d>", pict_id);


int main()
  char* gif_data;
  int gif_size;
  printf("Content-type: image/gif\n\n");
  gif_data = get_gif_from_db(&gif_size);
  write(1, gif_data, gif_size);
  return 0;

if this is unclear, e-mail me, and I'll answer in more detail.
