every few seconds, I want the same TImage to load a different jpg file but now it flickers whenever
TheImage.Picture.LoadFromFile('new.jpg');
How do I avoid the flickering?

I assume you're on Windows. Have you tried to set DoubleBuffered to True? I didn't use TImage, but I remember having to put the PaintBox onto a panel and set panel.DoubleBuffered to True to stop the flickering.

P.S. This is the wrong list for Lazarus questions.
