[TYPO3] IE 7 weird image rendering problem

[Bing Du]

Hi,

Typo3 V4.0.2
rtehtmlarea 1.3.7

The page with inline images shows up fine in firefox, Mozilla, etc.  But
in IE 7, all the inline images disappear.  Those images are inserted into
rtehtml directly.  There are other pages that also have inline images that
don't have any problem.  Just this page.  The weird thing is the missing
images are displayed fine in the backend rtehtmlarea editor fine.  They
just don't show up in the frontend.  The page source of one image is like
this.  Notice both width and height are 0.  The image itself can be viewed
fine in IE 7.  Its dimention is 405 X 290 pixels.

<p class="bodytext"><img src="/typo3conf/ext/tpg_iepngfix/spacer.png"
style="width: 0; height: 0; filter:
progid:DXImageTransform.Microsoft.AlphaImageLoader(src='/uploads/RTEmagicC_mail_setup_outlook.png.png',
sizingMethod='scale');" style="WIDTH: 405px; HEIGHT: 290px" alt="" /><br
/></p>

Anybody know why?

Thanks in advance.
