nice shade will become a black block, and the antialiasing is lost.

this is limitation of gif format, nothing can be done about it pixels in gif can be only full opaque or full transparent

remains an option), I don't know how to replace it with a color (like white) in images like wilber_the_gimp2.png where the transparency is progressive.

make a layer below the transparent image (background) with required color and flatten the image then

Would anyone help me / point me to ressources to solve either of these options?

the most elegant solution is to send png images with transparency to modern browsers and gif or nontransparent image to that microsoft garbage. if you place images on a page via CSS it is not hard to achieve (use child selectors for the things ie should not see)

Hi Karine,

Quoting Karine Proot :

* If I choose to remove the transparency (which is bad in itself but remains an option), I don't know how to replace it with a color (like white) in images like wilber_the_gimp2.png where the transparency is progressive.

To set the background to white, for example, while keeping the shades, you would create a new layer, put it underneath the wilber layer, and fill the layer with white. Then merging and saving as GIF should give you reasonable results (well, as good as possible with a 256 color palette). You could also convert to indexed at that stage and save as PNG which would be OK in IE, rather than using the GIF format.

Cheers,
Dave.

Hello list,

I just gave a look at my website using IE, and horror - I had forgotten it cannot handle PNG transparency. So of course one option is to ignore the problem and expect IE to be able to handle it somewhere in the future.

when you are saving your image as a png there is a dialog. one of the options on the dialog is "Save with Background Color", toggle that and make sure that the color of your web page is in the gimp's toolkit as the background color. ie will get the color from this information. unfortunately, it will not handle multicolor backgrounds.

it is a giant corporation who are paid well to meet your needs, the people who author this browser. perhaps you could ask them and let us know. i have never purchased or used their software (very much). did it come with a support phone number or email? this issue comes up often, if you could find out for us and let us know ....

Carol (sorry for being OffTopic again while replying to your request), I searched more and I finally found something :

http://support.microsoft.com/default.aspx?scid=kb;en-us;294714

Basically the support says "Use some proprietary method that no other browser will understand to get your transparency back in PNG."

it is on the border of being off-topic, it is an issue that affects people who use their computer to make graphics and view the internet with.

this internet explorer browser is so anti-american. forgive me for this. what i learned about my country in the education system that my country provided for me was that we were using capitalism as a method to build a strong country. the only thing i actually see going on is corporate welfare. where the big strong company needs government funding, your faith and compliance.

the mozilla people compete with themselves mostly. internet explorer doesnt feel any competition, sitting there fat and lazy slurping up government funding and your faith doing what? nothing.

this is not what they told me was going on when i lived in a capitalistic society. i dont even know if i want to live in one of those, i am just saying i have yet to see it.

bleh, sorry. carol

HTH, Michael

Thanks for the ressource, however I am a bit reluctant about adding so much code when all I wanted first was to display an image. I will rather make non-transparent PNG.

Have also a look at IE7.
http://dean.edwards.name/IE7/
http://dean.edwards.name/IE7/overview/ and here for the PNG transparency test: http://dean.edwards.name/IE7/compatibility/png.html

It is a set of CSS and javascripts/DHTML that makes IE follow the W3C standards (CSS1,2,3). It is quite amazing, and you do not have to modify much of your web pages (just 2 lines in the head section).

Olivier
