title: Reading all images(jpg) from a folder by using imageio.readvol()
body: <p>I can read all the *.dcm files from "imgs" with this command</p>
  
  <pre><code>vol = imageio.volread("imgs")
  </code></pre>
  
  <p>but I can't read jpg files. My image files has *.bmp.jpg extension (e.g. C001_IMG00023.bmp.jpg) and</p>
  
  <pre><code>histology = imageio.volread("imgs", "jpg")
  </code></pre>
  
  <p>command gave me </p>
  
  <blockquote>
    <p>RuntimeError: Format JPEG-PIL cannot read in mode 'v'</p>
  </blockquote>
  
  <p>then I read the docs and tried this command</p>
  
  <pre><code>histology = io.volread("imgs",mode="L", "jpg")
  </code></pre>
  
  <p>but it gave me this error</p>
  
  <blockquote>
    <p>SyntaxError: positional argument follows keyword argument</p>
  </blockquote>
  
  <p>I searched for the errors and about reading jpg files with imageio but i couldn't find anything about it. Is it possible to read image files from a folder with imageio or should I use different method for it? I want to read files with simple command like above.</p>
