Since LMD Tools 2012.1, ImageIndex property is used instead of ListIndex in TLMDBaseGraphicButton to define image taken from imagelist.

			This is made to make usage of two-dimensional imagelists consistent with one-dimensional imagelists.

			If you want to force former use of ListIndex in TLMDBaseGraphicButton, locate {.$DEFINE LMD_FORCELISTINDEXUSE} entry in lmdcmps.inc file and remove dot. In this case ListIndex will be used to define image index in one-dimensional imagelists like TLMDBitmapList, TLMDGraphicList etc, like it was in versions prior to LMD Tools 2012.1.
