Is it possible to save hidden text directly in a jpeg images header or to the jpg file?
// Write "copyright by XYZ" in 'alfa.jpg'
ImageEnView1.Proc.WriteHiddenText('Copyright by XYZ');
ImageEnView1.IO.SaveToFile('alfa.jpg');
// Read simple string from 'alfa.jpg'
ImageEnView1.IO.LoadFromFile('alfa.jpg');
mystring:=ImageEnView1.Proc.ReadHiddenText;

Thanks Nigel,
Yea, I am saving to EXIF Field now but I thought maybe it could be saved in the header, but I guess not.

Hi Bill
WriteHiddenText embeds the data within the image itself, so naturally it will not be compatible with a lossy format such as JPEG (as the hidden data would be corrupted).
But you could use EXIF or ITPC data fields and encode your data in some way.
