Missing images from ListView... :-(

Hi!

Sorry for my lamaism, but I have a program with images in a ListView.
I wanna show items as icons. Two bitmaps I load, but the images are not visible in the frame.

Please help me a little, if possible. Something missing, but I don't know, what is it... :frowning:

Thanks for your help:
