I heve conversion problems. HTML is created correctly but the images not.  I
tried various versions without success, now I have installed 99.2alpha9.  The
critical moment seems to be

extracting tex2html_wrap51 as 1#1Converting image #1

The image001.ps from dvips contains the original image surrounded with
grayness. /tmp/l2h23842/p23864.pnm made by gs contains only gray color and
pnmcrop can olny crop out everything. Maybe the translation or geometry is
wrong, I cannot find out where they are from. Some lines before I see

latex2htmlLength hsize=349.0pt

latex2htmlLength vsize=469.755pt

latex2htmlLength hoffset=0.0pt

latex2htmlLength voffset=0.0pt

latex2htmlLength topmargin=0.0pt

latex2htmlLength topskip=0.00003pt

latex2htmlLength headheight=0.0pt

latex2htmlLength headsep=0.0pt

latex2htmlLength parskip=18.0pt plus 4.0pt minus 4.0pt

latex2htmlLength oddsidemargin=0.0pt

latex2htmlLength evensidemargin=0.0pt

l2hSize :tex2html_wrap51:69.65546pt::0.0pt::349.0pt.

so I guess the numbers for pnmtops are maybe somewhat derived from above. The
original tex source is:

It is shorten LyX output. The image you get get via the Net if intererested:

Any ideas? The slides I am writing are in landscape mode. Maybe some rotation
problems? I will be happy to send you the whole log or whatever is needed to
solve the problem.
