Hola, tipicamente acá hay solamente personas de habla inglesa, así que más gente vendría con un post en inglés, pero dejame ver 😄

I think you need `using Images` as well.

Please read

> [@PSA: how to quote code with backticks](https://discourse.julialang.org/t/psa-how-to-quote-code-with-backticks/7530):
>
> This is a short post on how to use backticks (` and ```) to quote code, so it is easy to read. This post can be linked to new users who are confused by this feature. Why By quoting your code, you get a monospaced font (which preserves indentation) and syntax highlighting. This makes it easier to read your code and help you. Displayed code looks like this: function displayed\_code(x::Int, y::Int) if x \< y println("x is smaller") else println("or not") end end Inline…

(Efectivamente aquí suele haber posts sólo en inglés.  
Creo que necesitas `using Images` también.)

</div>

prueba esto, debería funcionar

```julia
using ImageView, TestImages
img = testimage(“mandrill”)
imshow(img)

```

Actualización, no requiere el paquete Images para la visualización, ImageView es necesario
