In the meantime I have solved part of the problem, by deinstalling
Greenstone on my home computer and after reinstallation it is now
exploding the database, but I also found that with our photo database
containing 1033 photos, that after the process not all the records
have linked to the image, but it just creates .nul files, although
the image is in the directory indicated in the prefix. I will
download the new explode database script.
My date lists are now also working after the reinstallation.

When building a collection on another computer to be transferred to a
public server, what folders are necessary for the collection to work
on the server?

I have used the manual by John Rose, etc. on the exploding of ISIS
databases. It is very useful
>http://greenstone.sourceforge.net/wiki/gsdoc/others/CDS-ISIS_to_DL.doc


On the collection's page there is the text "How to search the ....
collection." Where is this text
so that I could edit i?

Thanks for all the help.
Regards
Renate
