Hello and thanx for all the replies.

I am currently unable to find an answer to the ques 2 and 3 i posted above. On searching i have come across websites that offer to convert image for me to ascii or binary but i want an algo to do that embedded inside the applicaton that i create. Although i searched a lot but still i am unable to find an algo for conversion.

Please specify an algo for the conversion and some info about the format of the jpeg.
The wiki link was a good one.

Thanx
