List View Icons

[Technocrat]

I have a list view that I am listing files in a directory along their the corresponding icons. The problem I have is that some of the icons are not getting a transparent background (see attached).

The window is a modal dialog with the ListView control on it.

I am using:
g_hImageLst = ImageList_Create(16,16,ILC_MASK | ILC_COLORDDB, 1, 0);
To setup my ImageList

I am using:
ListView_SetExtendedListViewStyle(hWnd,LVS_EX_SUBITEMIMAGES);
To setup the list view

Then:
SHGetFileInfo(dirInfo.cFileName,FILE_ATTRIBUTE_NORMAL, &shInfo, sizeof(shInfo), SHGFI_USEFILEATTRIBUTES | SHGFI_DISPLAYNAME | SHGFI_TYPENAME | SHGFI_ICON | SHGFI_SMALLICON);
To Get The Files Icon

Finally:
ImageList_AddIcon(g_hImageLst, hIcon );
ListView_SetImageList(m_hWnd, g_hImageLst, LVSIL_SMALL)
To push the icons on the list and set the list.

Any suggestions on how to fix the icons so they look better?
