[l2h] Some png do not match with ps files

[Jose Luis Gallego]

Dear all,

Sometimes the conversion of ps files into png files (under w2k) does not
work properly for me. For each ps file there is a png file, but some of them
do not match. The images.dvi file is fine, but not the final html file.
Something similar happens in the conversion of math symbols: \delta is shown
instead of \theta. Any idea?

Thank you,

Jose Luis
