Hi Dan, Please send your messages via the list - that way you are picking more brains simultaneously ! > I tried running the imageLab but got the errors listed below. It appears the code is trying to make a connection "jdbc/EPSG". > Not sure why the code is trying to connect to EPSG. How can I get around this? Are you using Maven or are you adding all of the GeoTools jars to your project manually ? >From the errors below I'm guessing that you're doing the latter. If that's the case, and you really don't want to use Maven instead, then please have a look at the Quickstart workbook on this page: http://geotoolsnews.blogspot.com/2009/11/foss4g-geotools-tutorials.html There is one for Netbeans and one for Eclipse. Both include a section about adding jars manually and tell you what jars *not* to add. If I'm on the wrong track, or this doesn't help, please get back to the list with a bit more info about the image that you're trying to load: format, size, any special attributes etc. Michael > > Dec
