Good luck.

You can't, because it isn't loaded from a file. It's streamed from a resource along with the rest of the form.

TPicture has a LoadFromFile method which takes a file name, decides what sort of TGraphic is needed to load that file, and then creates that class of TGraphic and calls its LoadFromFile method. While you could capture the file name at several points along the way here, there seems to be no point in doing so. Internally Delphi never does a LoadFromFile; only your code will. Since your code already knows the name of the file, why make it difficult and force TPicture to determine and remember what you already know? Good luck.

I'am working on a component that will enable design of Delphi standard components(TStaticText, TDBEdit,TMemo,...) in runtime. The user will determine font,size,position,.. of these components. Then all user settings will be saved in ini file (more than one layout/design). So when I'am loading or saveing in ini file, i need some info about image file. (I'am using TImage on TPanel for image component) Any work around would be nice! Regards Milos.

So when I'am loading or saveing in ini file, i need some info about image file. (I'am using TImage on TPanel for image component) Let us suppose for the moment that you were able to capture the file name for a TPicture and save that name in your .ini file. The next day, the user opens this .ini file, your code sees the reference to 'c:MyBitmap.bmp' and tries to do a LoadFromFile. But since yesterday, the user cleaned up his hard drive and that file is no longer there. Why do you think Delphi stores the content of the TImage at design time in the .dfm file? Precisely so that the user can't shoot himself in the foot. Good luck.
