[MiKTeX] transparent png in pdflatex

[William D. <wil...@ty...>]

Hi all,

I wish to use transparent png using pdflatex. Pdftex 1.21b is capable of
using transparent png. However, the current version of pdftex in MikTeX uses
1.21a does anyone know of a work around that can introduce transparency? As
I am not an administrator simply installing png2pdf to obtain a transparent
pdf image is not an option (IT dept. very fussy)! Any help gratefully
