[Getdp] WaveEquationPml

There is even the tex source in the "alt=" declaration, so while using our all favorite text-mode browser lynx, it is somehow readable. "Screenshot" :)

However, I just fired up IE (6.0, WindowsXP) for the first time in one year, and right, it _still_ has problems with displaying transparent png files. Incredible. 
A (unnelegant) workaround would be to make the png's being rendered opaque, but one should not be spending time fixing bugs of old browsers.

nice greetings,
 Bernhard

Illegible? Maybe the image is too small. Or maybe you should give firefox a 
try.

Anyway, you can work around this problem: if you click "edit" on the web page, 
you will see the wiki markup wich include the latex equations. Copy these equations in a tex document will allow you to produce a dvi or pdf 
document.
