You can try dExif https://github.com/cutec-chris/dexif/blob/master/ProgrammerGuide.Txt

You could maybe use the EXIF library, see the thread below

You could maybe use the EXIF library,

I was going to suggest the same: fpexif, because I had some problems with some Delphi-specific* sections of dExif.

Though that was some years ago; it may well be corrected by now ...

* TBH, I don't remember if it was Delphi-specific or some breaking changes in Lazarus/FPC. I think is was the first, but I might be wrong.
