I am not completely sure how these two specific programs from the
gdal package relates to the challenge of outputting a png from 2
shapefiles (map and legend).
ogrinfo can be used to give a report on the type of coordinates
being used in your shapefile. You can 'cd' into the directory of
your shapefiles and then type:
ogrinfo yourshapefilename.shp -so -al
This should give you a short report. When asking for help you can
include this report and others will see more information about your
dataset without having to download it.
Splendid. Thanks.
gdalinfo operates a similar way but for images and rasters. This
may not apply to you at the moment.
Right.
You can read more about these tools and more in chapter 3 of my book:

Fortunately some of these examples are included in the free online
chapter at http://oreilly.com/catalog/webmapping/chapter/ch03.pdf !
(around book page 30)
Hope this helps. Enjoy,

I am learning new thing with every new email, yes. Thank you for the
reference to your book.
It looks increasingly like I have to dive in to the workings of the
geoserver to be able to output png files of a mashup between my
geotagged images and my maps.
Having participated once in a OpenStreetMap mapping session, I wonder
if OSM is run on top of GeoServer and could be used together with i.e.
OpenLayer to do what I want? Still - downloading and installing
everything needed, seems laborious compared to a simple conversion
from shapefile to png.
Any particular reason why a simple conversion between shapefile and
png seems so cumbersome to do via a simple program accessible through
the command-line?
Hm... Not sure I am out of the woods yet, as a png seems a long way off.
