Hi Senthil,

Take a look at The Crypto++ Library.

Thats a free library and the usage is relatively simple too.

Do remember that if you encrypt the JPG file, the resultant file will not be a standard JPG file.

There are various algorithms available for encryption that one can use. The Crypto C++ library as mentioned in the previous post does implement most of the popular algorithms.
