TImage descendant remains black after loading dfm

[djBo]

Hi List,

I have just created a TImage descendant that is able to make a
connection to a TImageList.
I have the property editor etc all in place, and even have made id so
that it either saves Picture.Data OR ImageIndex/Images to the DFM.

Question:
If it has a TImageList connection the image remains black after
loading the form in the IDE.
Which method do I need to add/override/whatever in order to load my
image in designtime?

Thanks in advance,
Rory
