Once you've performed all your operations on the image object, dump the bytes out.

// assumes PNG to JPG, no exception handling, just raw example
// load in a PNG
src, _ := imaging.Open("sampleimage.png")
// resize it
dst := imaging.Resize(src, 250, 0, imaging.Lanczos)
// get a bytes buffer container
buf := new(bytes.Buffer)
// use jpg encode ( assuming JPG ) and push the bytes out to the buffer
jpeg.Encode(buf, dst, nil)
// dump out the bytes to a file
ioutil.WriteFile("sampleimageout.jpg", buf.Bytes(), 0644)
