Summary 0006564: JvDBImage shows "Bitmap image is not valid" to some kind of jpeg image.
Description Some kind of jpeg image does not has the "JFIF" or "Exif" signature at stream offset 6 as procedure GraphicSignaturesNeeded expected.
Additional Information Simple workaround is to add:

    RegisterGraphicSignature([$FF, $D8], 0 , TJPEGImage);

to

procedure GraphicSignaturesNeeded;

But I think we should add file ending signature examination since a valid jpeg file is always ended with 0xFF, 0xD9. (According to https://en.wikipedia.org/wiki/JPEG) [^]
