+To make an `HBoxContainer` dynamically resize with its image contents in Godot 4.3, follow these steps:
+
+## Core Setup
+- **Parent with `ScrollContainer`**: Place your `HBoxContainer` inside a `ScrollContainer` to enable scrolling when content exceeds visible area. Set the scroll direction (horizontal/vertical) in the `ScrollContainer` properties[5].
+
+- **Container Settings**: 
+  - Enable `Expand` and set **Stretch Mode** to `Keep Aspect` on all child `TextureRect` nodes[2].
+  - Apply **Size Flags** (`Fill` and `Expand`) to each `TextureRect` to ensure proportional scaling[2][3].
+
+## Dynamic Resizing
+For automatic width adjustment when adding/removing images:
+```gdscript
+# After adding/removing children:
+$HBoxContainer.queue_sort()  # Forces layout update
+$ScrollContainer.update_scroll()  # Refreshes scroll boundaries
+```
+
+If automatic resizing fails (common with dynamic content), manually calculate and set the container width:
+```gdscript
+var total_width = 0
+for child in $HBoxContainer.get_children():
+    total_width += child.size.x
+total_width += $HBoxContainer.get_constant("separation") * ($HBoxContainer.get_child_count() - 1)
+$HBoxContainer.custom_minimum_size.x = total_width
+```
+
+## Alternative Approach
+For wrapping behavior, replace `HBoxContainer` with an `HFlowContainer` (ensuring it's inside a fixed-size Control node). This automatically wraps overflowing items to new rows while scaling contents[2][4].
