Subject: poppler-utils: "pdftohtml -s <file>.pdf" produces multiple files.

Dear Maintainer,

*** Reporter, please consider answering these questions, where appropriate ***

   * What led up to the situation?
   pdftohtml was applied to a pdf file containing pixmap images.
   
   * What exactly did you do (or not do) that was effective (or ineffective)?
   The command was "pdftohtml -s <file>.pdf".
   
   * What was the outcome of this action?
   All the text was in one <file>.html but each picture was an additional file.
   
   * What outcome did you expect instead?
   With the -s option, text and pictures should all be in one <file>.html.
   A JPEG or PNG picture can be included in an html document with Base64 
   encoding.  The syntax is very simple.  Examples here.
   http://easthope.ca/Category2.html
   Scroll down to the heading "Inline, Base64 encoded PNG bitmaps".
   The first instance of an embedded bitmap is 
   <img src="data:image/png;base64,iVBORw0K ..."
   alt="Diagram for 0x0 with test object 0,<br>represented in PNG.<br>">
