As Tanya suggested, you could use the RadImageEditor's format providers in order to import/export
images. If you have exported the image to byte, you could check this article on StackOverflow
about converting byte array to a stream. In addition, you could use the format provider's overload of the Export() method which gets as a parameter a stream object in which the image shall be written.
For your convenience, I've created a sample demo project which uses the second mentioned approach. You can find it attached.
I hope this helps.
