RE: IE7 PNG Images Do Not Display

I have the similar problem when I using the HTML help workshop to compile a
help file which contains multiple web pages and images like PNG, BMP, JPG and
GIF. When I run the help, the images are blanked out, except BMPs, with a red
x. Try on other machine with similar Xp OS, problem continues. But It work
perfectly well if I run it in another computer with Vista Ultimate running.

I guess it is the IE causing the problem, how can I fix this.

Thanks

Try something here:

Open the Run box and enter: regsvr32 %WinDir%\system32\pngfilt.dll

Get a registry fix file here (XP and Vista):
PNG images are not displayed on Web sites in Internet Explorer

Internet Explorer doesn't display PNG images even though your web page claims it supports PNG. What's up with that?

I have tried those method, problem persisted.

The fact is that the IE does display the images when I browse them page by
page, which were generated by Word 2003. When I attemp to run the the
compiled .chm help file, it shows only a placeholder in the place of an
image.

Please kindly suggest a solution.
