William Hello Again one by Please Help a Friend.

I did upload a problem that I found in a sample ImageEN when working with Preload

you to identify the error is easily the listbox simply moves up and down really fast forcing load the images and you will see that imageenview1 imageenview2 turns black and does not load the image correctly, I would like to know when imageenview2 uploader to use real assigned?

To fix your problem change
procedure TForm1.FileListBox1Change(Sender: TObject);
begin
  GetImage(FileListBox1.FileName);
  PrepareNext(FileListBox1.ItemIndex + 1);
end;

To
procedure TForm1.FileListBox1Click(Sender: TObject);
begin
  GetImage(FileListBox1.FileName);
  PrepareNext(FileListBox1.ItemIndex + 1);
end;

Hello William Thanks for your attention.
But unfortunately the problem persists even black bears sometimes the image, simply click fast or load images with large dimensions.
I really need to know when imageEN fills the entire image?

I can not repeat your problem no matter how fast I click even with 18 mp. pictures. I never get a black image. Anyhow, maybe try OnFinishWork to know when image is finished loading.
