I don't know the reason, can anyone brief me?
GIMP saves the PNG als a full RGBA image by default, IE can't handle 
this without hacks in the HTML file. gif2png converts to PNG without 
changing the mode (like ImageMagick or GraphicsMagick do, too).

Can we add an option to GIMP to let it create the png that is 
transparency-compatibile with IE?
The option is already there, you have to convert your image to indexed 
mode before saving.

HTH,

[Gimp-user] IE deals with png transparency?

2004-04-08 Thread Zhang Weiwu

and (as expected) I lose transparency on IE.

But later I tried another tool, the gif2png by Eric Raymond, 
surprisingly the created png still can display transparent area on IE 
(I'm not sure if it is transparent area or alpha channel, most likely 
just transparent area), although on some friends' IE the png is 
undisplayable at all, but most Windows computers display the 
transparency just fine. An example image is the logo on my homepage
my homepage: http://aliweekly.nease.net/
the image: http://aliweekly.nease.net/images/headline.png

I don't know the reason, can anyone brief me?
