Fot his example you start with top domain model and map it with inner collections called Nested mappings.
mapper.CreateMap<Word , LanguageViewModel>()
.ForMember(dest => dest.Name, src => src.MapFrom(s => s.Text));
For inner collections within Word domain model, you need to define separate mappings for Categories and Pictures.
mapper.CreateMap<Picture, PictureModel>()
.ForMember(dest => dest.PictureURL , src => src.MapFrom(x => x.Picture.Urltext));
mapper.CreateMap<Category, CategoryModel>()
.ForMember(dest => dest.CategoryId, src => src.MapFrom(x => x.Category.CategoryInt));
and for all remaining inner collections you need to define mapping to make it work
