Arduino student kit lessons

first of all i didn't know which category fits my question so im sorry for that, so i bought the arduino student kit recently and while i was viewing the lessons i noticed that the images wont load, i tried different browsers to see if that solves it but the same problem happened in every single browser i tried, does anyone know how to solve this?

The Spanish section where you created your other topic is probably the best place to continue this so I have locked this one
