+In this lesson, you will write the code to change the expressions of the characters when clicking the buttons.
+
+Loading image at compile time (advantage of seeing error if file doesnt exist)
+```python
+var image := preload("res:://image.png")
+```
+
+
+Loading at runtime on demand:
+```python
+load("res:://image.png")
+```
+
+
+
+
+Preloadingloading into a dictionary:
+```python
+var bodies := {
+	"sophia": preload("res://assets/sophia.png"),
+	"pink": preload("res://assets/pink.png")
+}
+```
+
+Dont forget to multiselect + drag&drop assets into code editor, then multi-cursor correct using 
+either Alt+Ctrl+Mouseclicks, or Alt+Shift+Cursor Up/Down
+
+
+*Setting TextureRect texture*
+```python
+func _ready() -> void:
+	body.texture = bodies["pink"]	
+	expression.texture = expressions["happy"]
+```
+
+
+It's not mandatory to use square brackets to access dictionary values. You can also use the `.` operator. For example, writing `bodies["sophia"]` is equivalent to `bodies.sophia`.
