Does anybody have a reliable way to determine if a TImage, or any of
it's descendants, actually contain graphical content? I've been
ploughing through the methods, but can't seem to find anything. (I'm
fairly sure I never solved this in Delphi either!!)

Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i function
IsEmpty(aImage:TImage):Boolean;begin  Result := aImage.Picture.Graphic
= nil;end;

Thanks taazz - will try this later tonight (when I get my programming
head on)! 
Have now checked this and it seems to work fine - NOT tested
exhaustively, but shouldbe good enough for my needs - thanks again
