[l2h] Problem with pictures and equations

[Andrea Gaggiotti]

Hello!

I have a problem with equations.

Equations are  mixed in my final html document.
Some of them are not in the correct place, and they are in the place of 
another equation.
I don't understand how to correct this behaviour.

I searched in the archive and I found a way to resolve the problem: to put 
a different label in every equation.
But this trick does not work!

Can anyone help me?ù
Thanks
