How do I create a RGB png image which has a transparent background?
From http://www.cdrom.com/pub/png I understood (?) that I need to add an
alpha channel. So I clicked on Image->Alpha->Add Alpha Channel. Next I
selected the regions to be made transparent, and clicked on
Image->Alpha->Threshold Alpha. Okay, the regions are now as transparent
as I want them to be in gimp. Now I saved this image.
After that I wrote a real basic html file which uses this image with
<img src="...">. When I load this page in Netscape v4.7 I don't see
any transparency at all. Reading further on cdrom.com I found that
Netscape's alpha channel support is broken.
Is this still true, and are there any plugins for Netscape (Linux) that
add full alpha channel support?
