AdvSmoothListBox, imagelist and PNGs: how to?

VCL TMS VCL UI Pack

I need to have an image (PNG) that show the "expanded" status of the items.
I'd like to change the image using the GraphicLeftIndex property (0=closed,1=expanded).
To do this, i suppose that i need to assign an imagelist to the Images property of the TAdvSmoothListBox, but standard imagelist does not handles PNGs. The TGDIPPictureContainer handle PNGs, but it is not listed in the object inspector TAdvSmoothListBox->Images dropbox.
So, what should i do?

Thanks

Please use the picturecontainer property on the listbox to assign a GDIPpictureContainer

The GraphicLeftIndex is used for the imagelist and the GraphicLeftName property is used with the picturecontainer
