I am creating a user login, but I want to create a user image, as a base image, when I create the created user, by this I mean for example facebook , that at At the moment you create an account, a pictogram of a man or a woman appears as a profile picture, I want to do something similar in my login, could someone guide me on how to do it? here the code that generates the user.

token, _ = APP.Jwt.GenerateToken(jwt.MapClaims{
    "iat": APP.Jwt.GenerateIAT(),
    "exp": APP.Jwt.GenerateEXP(),
    "iss": APP.Jwt.GenerateISS(),
    "aud": APP.Jwt.GenerateAUD(),
    "jti": APP.Jwt.GenerateJTI(),
    "sub": APP.Jwt.GenerateSUB(),

    "id":        u.ID.Hex(),
    "email":     u.Email,
    "phone":     u.Phonenumber,
    "username":  u.Username,
    "bio":       u.Biography,
    "age":       u.Age,
    "nickname":  u.Nickname,
    "createdAt": u.CreatedAt,

You create your Nuevo function within the Usuario package, receiving as parameters the fields you request when creating the user. Taking for example that your fields are: "name" and "password".

package usuario

const imagenDefault string = "<Path a tu imagen>"

//Usuario estructura con la informacion de Usuario
type Usuario struct {
    Nombre     string
    Contrasena string
    Imagen     string
}

//Nuevo retorna el apuntador del objeto de un nuevo usuario
func Nuevo(nombre, contrasena string) *Usuario {
    var nuevoUsuario = &Usuario{
        Nombre:     nombre,
        Contrasena: contrasena,
        Imagen:     imagenDefault,
    }

    return nuevoUsuario
}

And to send it to call would be something like this:

package main

func main(){
    var adminUser = usuario.Nuevo("admin", "admin")
}

If you want to use Go's image package, it would be better so you do not have to depend on the direct path of your image.

Package image implements a basic 2-D image library.

The fundamental interface is called Image. An Image contains colors, which are described in the image / color package.

So you can read the image and save the byte array corresponding to your image, although that depends more on the needs and resources you have.
