1. Spaces in file names?
   "file width.png"
2. What should be the end of the file name?
   a) End marker
      * space (see problem 1.)
      * space + width/height/depth
      * special character
        \pdfimage Begin...EndOfFileName^^A width...
        \pfdimage Begin...EndOfFileName WithSize width...
        (the file name must not contain "WithSize" or ^^A.)
   b) Marks like \verb: \pdfimage +Begin...EndOfFileName+ width...
      The + can be replaced by any other character. But this character
      must not appear in the file name.
   c) Curly braces (\catcodes 1, and 2)
      \pdfimage{Begin...EndOfFileName}width...
