Does this hint make sense?

I've got a program with two units:
Uni1 is a datamodule that contains a TImageList called
#ImageList#Unit2 holds a form with a Ttreeview called #TreeView#.
TreeView.Image points to #ImageList# in Unit1
The compiler produces the following hint:
Hint: unit "Uni1" not used in Unit2

If that's true, how are the images in the data module loaded in the
form at run-time? The lfm file of unit2 clearly shows that the images
are not copied into the form at design time.

What am I missing?

Thanks for any insight.

Since property values are written in lfm file and not in the code,
compiler does not have information about stored property values at
compile time and hence this message.
If I remember correctly, you don't need to add unit1 in uses section
of unit2 if the unit1 is used from another place (e.g. in the uses
section of the main project file), but then there may be problems at
design time.
However, Lazarus could hide this message in this case.
