New Logo

[José Roca]

 
Problem solved. IE6 users will see the old logo and the others the new logo.

I have modified the index template from

   {
      if (empty($settings['header_logo_url']))
         echo '
                  <a href="', $scripturl, '"><img src="', $settings['images_url'] . '/'. $settings['theme_main_color'], '/logo.jpg" style="margin: 0px;" alt="', $context['forum_name'], '" title="', $context['forum_name'], '"/></a>';

Everybody happy?

PS Tested with FireFox, Opera and Internet Explorer 6.0.

Is the original Logo a jpg or png? I thought jpg didn't support transparency?
Anyways nice to see how to code that sort of fix, thanks Jose!

[José Roca]

 
The original logo is a transparent .gif. I did it with an icon editor, just to have something to show. Patrice's logo is a transparent .png, that can handle progressive opacity and more than 256 colors.

Jose, you are amazing again.
Now you get even a web-programmer in your spare-minutes. :-)

José

If I remember well you also speak french, don't you? 

Here is the solution to display correctly transparent PNG even with IE6...
Java script

[José Roca]

 
Mais oui, but the theme is written in php, not html. Anyway, IE6 users visiting this forum will we few.

[Theo Gottwald]

I would also favour php because the JAVA Script is disabled if the browser settings are set to safe.
PHP should work under any conditions as its server based.

[Patrice Terrier]

Then here is a PHP solution
PNG in PHP

Note: they improperly speak of PNG 24-bit, but indeed they should write PNG 32-bit.
24-bit has no room for the alpha channel, it must use full ARGB  instead of RGB.

If interrested I can show you how to display full 32-bit ARGB image preserving the alpha channel.

Don't force me to do many changes. The template isn't mine and with every version of the forum software I have to install a new version of it and redo the changes, and I have no idea of php programming.

[Theo Gottwald]

As said, actually it works perfectly.
Never change a running system ..? :-)
