title: invalid JPEG format: missing SOI marker
body: <p>Trying to decode an image and write to a file.</p>
  
  <p>This is my code:</p>
  
  <pre><code>package main
  
  import (
          "bytes"
          "fmt"
          "github.com/reteps/gopowerschool"
          "image/jpeg"
  )
  
  func main() {
          client := gopowerschool.Client("https://example.com")
          session, userID, err := client.CreateUserSessionAndStudent("username", "password")
          if err != nil {
                  panic(err)
          }   
          response, err := client.GetStudentPhoto(&amp;gopowerschool.GetStudentPhoto{UserSessionVO: session, StudentID: userID})
          if err != nil {
                  panic(err)
          }   
          fmt.Println(string(response.Return_))
          image, err := jpeg.Decode(bytes.NewReader(response.Return_))
          if err != nil {
                  panic(err)
          }   
          fmt.Println(image)
  
  }
  </code></pre>
  
  <p>The image is:</p>
  
  <pre><code>/9j/4AAQSkZJRg....VNpSP8f6VmE4oopks//Z
  </code></pre>
  
  <p>It is giving me an error when I try to decode the []byte of the image. </p>
