Unable to open Image in C++ SDL -

so im trying render image. code worked fine before refactored seperate classes cannot see problem. file path image worked before refactoring have not moved image should still in same place.

the error getting "unable create texture surface. error: couldn't open images/text.bmp" im line of code below messing up.

if (!(gtexture->loadfromfile("images/text.bmp")))         {             return false;         } 

here loadfromfile function code

bool texture2d::loadfromfile(string path) {      free();      sdl_texture* ptexture = null;      sdl_surface* psurface = img_load(path.c_str());      if (psurface != null)     {         //sdl_setcolorkey(psurface, sdl_true, sdl_maprgb(psurface->format, 0, 0xff, 0xff));          ptexture = sdl_createtexturefromsurface(mrenderer, psurface);         if (ptexture == null)         {             cout << "unable create texture surface. error: " << sdl_geterror() << endl;         }          mwidth = psurface->w;         mheight = psurface->h;          sdl_freesurface(psurface);     }     else     {         cout << "unable create texture surface. error: " << img_geterror() << endl;     }      mtexture = ptexture;      return ptexture != null; }
