I'm trying to convert some images for my game's assets but for some reason al_save_bitmap is not working. I have called al_init_image_addon during startup. Below is the offending code:

#SelectExpand
  1oid ConvertUnitSmallImages( void )
  2{
ALLEGRO_BITMAP *tmp = al_create_bitmap(320,128);
if ( !tmp )
  return;
for ( UInt type = 0; type < 18; type++ )
{
  ALLEGRO_STATE state;
  al_store_state(&state,ALLEGRO_STATE_TARGET_BITMAP);
  al_set_target_bitmap(tmp);
  al_clear_to_color(al_map_rgb(255,0,255));
  UInt x = 0;
  UInt y = 0;
  for ( UInt direction = 0; direction < 4; direction++ )
  {
    for ( UInt side = 0; side < 7; side++ )
    {
      for ( UInt frame = 0; frame < 2; frame++ )
      {        
        DrawSmallUnitEx(type,side,direction,frame,x,y,32,32,0);
        x+=32;
      }
    }
    y+=32;
    x = 0;
  }    
  al_restore_state(&state);
  al_draw_bitmap(tmp,0,0,0);
  al_flip_display();
  String fileName = "./gfx/Units/Small/New/";
  fileName+=g_UnitFileNames[type];
  fileName+="N.bmp";
  if ( al_save_bitmap(fileName.c_str(),tmp) )
    std::cout<<"Image saved to: "<<fileName<<"\n";
  else
    std::cout<<"Image NOT saved: "<<fileName<<"\n";
}
al_destroy_bitmap(tmp);
tmp = NULL;
 40}

Does the /gfx/Units/Small/New/ exist? Also, try making a file using al_fopen(fileName.c_str(), "w") and see if that returns a non-NULL.

Both give an error. And yes, gfx/Units/Small/New exists. I've even tried to run as administrator thinking write permissions, but still can't.

Edit:
On a side note, I am using the physfs interface as well...even though I don't think that should hurt in this case. Maybe it's making things read only...

Edit 2:
It was PhysFS setting the directory read only....

al_save_bitmap not working!
