The DLGBITMAPLISTITEM structure contains information about a bitmap referenced by the DLGBITMAPLIST structure.

Member	Description
uStructSize	Size of this structure, in bytes. Use the sizeof operator to calculate this value.
pBitmap	Ignored.
	This bitmap may be the bitmap to use for processing or a thumbnail of it. The thumbnails are used for preview purposes only. The corresponding original bitmaps are used in processing. The original bitmaps are identified by the pszFileName member. If the bitmap is a thumbnail, pszFileName should be a valid fully qualified path name. If the bitmap is not a thumbnail, pszFileName should be NULL.
pszFileName	String that contains the name of the file that contains the bitmap referenced by pBitmap.
	Set this field to a fully qualified path name if you wish to supply a thumbnail for previewing purposes only. This fully qualified path name will be used to load the bitmap when needed. Set this field to NULL to indicate that the bitmap set in the pBitmap field is not a thumbnail but is the bitmap to be used in processing.
	Notice that some dialogs ignore this field and use the bitmaps set in the pBitmap field.
pszDescription	String that contains the text that will be used for special purposes by specific dialogs. For more information, refer to the documentation for the structure associated with the specific dialog.
