Question:
How can I change the TDBNavigator button images?
Answer:
Provide bitmap files 'first.bmp' etc (see code below; it assumes that the bitmaps are in the directory where the .exe file resides) and use the procedure ChangeDBNavImage like this:
ChangeDBNavImage(DBNavigator1);
The code looks through the child objects for the TNavButton and assigns each bitmap.

procedure ChangeDBNavImage(DBnav: TDbNavigator);
var
i: integer;
tempGlyph: TBitmap;
ExePath: string;
begin { ChangeDBNavImage }
ExePath := ExtractFilePath(Application.ExeName);
tempGlyph := TBitmap.Create;
try
with DBnav do
begin
for i := 0 to ControlCount-1 do
begin
if Controls[i].ClassName='TNavButton' then
begin
case TNavButton(Controls[i]).index of
nbFirst:
tempGlyph.LoadFromFile(ExePath+'first.bmp');
nbPrior:
tempGlyph.LoadFromFile(ExePath+'previous.bmp');
nbNext:
tempGlyph.LoadFromFile(ExePath+'Next.bmp');
nbLast:
tempGlyph.LoadFromFile(ExePath+'Last.bmp');
nbInsert:
tempGlyph.LoadFromFile(ExePath+'Insert.bmp');
nbDelete:
tempGlyph.LoadFromFile(ExePath+'Delete.bmp');
nbEdit:
tempGlyph.LoadFromFile(ExePath+'Edit.bmp');
nbPost:
tempGlyph.LoadFromFile(ExePath+'Post.bmp');
nbCancel:
tempGlyph.LoadFromFile(ExePath+'Cancel.bmp');
nbRefresh:
tempGlyph.LoadFromFile(ExePath+'Refresh.bmp');
end; { case TNavButton(Controls[i]).index }
TNavButton(Controls[i]).Glyph := tempGlyph; // <-- Assign the loaded bitmap
end; { Controls[i].ClassName='TNavButton' }
end; { for i }
end; { with DBnav }
finally
tempGlyph.Free;
end; { try }
end; { ChangeDBNavImage }
