Image Encoding

Question

Hi
I have an xml file and I read my data from it, but my question is:
how can I encode the image and then write it into this file? since I want to let my application read the encoded image from the xml file and then store it to Record Store.
Please any help will be so appreciated :(
thanks in advanced

I searched for another code and i found this code and it's work fine :)
