title: How to instruct convert to resize only first TIFF frame if file path specified?
body: <p>I tested some code which works fine:</p>
  
  <pre><code>C:\root\Dropbox\WWW\TIFF\sandbox 17:17:37,86
  $c:\cygwin\bin\convert.exe gallery.tif[0] -thumbnail 300x300^ -format jpg gallery.jpg
  </code></pre>
  
  <p>But I want to specify full path to image and it is not works - why it is not working?</p>
  
  <p>It is the same image.</p>
  
  <p><code>c:\root\Dropbox\WWW\TIFF\sandbox\gallery.tif[0] == gallery.tif[0]</code> - why it is not working?</p>
  
  <pre><code>C:\root\Dropbox\WWW\TIFF\sandbox 17:17:59,29
  $c:\cygwin\bin\convert.exe c:\root\Dropbox\WWW\TIFF\sandbox\gallery.tif[0] -thumbnail 300x300^ -format jpg gallery.jpg
  convert: must specify image size `\root\Dropbox\WWW\TIFF\sandbox\gallery.tif' @ error/raw.c/ReadRAWImage/136.
  convert: no images defined `gallery.jpg' @ error/convert.c/ConvertImageCommand/3210.
