Hi Lucia,

You can use the "-document_field" option to obtain (download) the images
when exploding the database (set it to "Identifier" if this is the field
that specifies where the images are). The images will become the
documents in the collection, and the metadata will automatically be
added to the images. When you build the collection the images will be
processed by ImagePlug and it will create thumbnails for you.

Try this with Greenstone v2.63 if you like but if you have any problems
please try Greenstone v2.70 (due in a couple of weeks), as I've made a
lot of improvements to the exploding and CDS/ISIS code recently.

Are you able to send me (personally) your database so I can try it here
and make sure what I've described works?

Regards,

Michael
