Yes exactly I am makign my school project on this topic.

I have embed text into file but while reading text back I am getting problem. How can I get orginal length (size) of file?

for example

i have new.jpg- 32KB
I embed msg into it and save it to new1.jpg

new.jpg and new1.jpg are exact same while i open in paint. Now how can I get msg from new1.jpg?
