[l2h] Relative/Absolute paths of images and failure when the images are accessed by the variable $TEXINPUTS

[Mark Duke]

Hi Ross and Nasser and community,

Thanks first of all for your help!

@Ross - the idea with the symbolic links would be fine, but the 
generated files are not on the web, but should be machine independent 
and be accessible on any machine independent of the web, which is why 
all paths have to be relative.


I have effectively the same problem as addressed by the following 2 threads:
http://www.mail-archive.com/latex2html@tug.org/msg01914.html
http://www.mail-archive.com/latex2html@tug.org/msg01915.html

The second answer with modifying $COPY_GRAPHICS=1 in graphicx.perl has 
helped me a lot. The files are now copied to the html output directory 
and are referenced relatively :-) . This only works, however, if the 
path to the images are entered directly in the includegrpahics command:
\includegraphics{./mypics/install_lic_webfront_mypics}
If I try and access the files via either the $TEXINPUTS (which 
previously worked with my eps files) or with the 
\graphicspath{{./mypics/}} then the translator tries to convert the 
pictures and the converted picture (conversion is not necessary; it's 
only needs to be copied) is a corrupted png :(((((

If I could just get the $TEXINPUTS or \graphicspath to work then things 
would be great. Do you have any other ideas? Or has anyone else had this 
problem?

Thanks loads in advance,

Mark
