I would use the COPYRECT method.  An example:

DestRect.Left := 0;
DestRect.Top := 0;
DestRect.Right := 50;
DestRect.Bottom := 50;
SourceRect.Left := 0;
SourceRect.Top := 0;
SourceRect.Right := 50;
SourceRect.Bottom := 50;
Image1.Canvas.CopyRect(DestRect, Image2.Canvas, SourceRect);

This would copy a 50x50 square from the top left corner of Image2 into Image1.

Hmm after looking in the help file it looks like it would be easier doing:

DestRect := Rect(0, 0, 50, 50);
SourceRect := Rect(0, 0, 50, 50);

(They are both of type TRect BTW)
