Hi mike,

I think the 'Loci-Bioformats' plugin for imageJ can open openlab liff 
files.  Download from the website below:

http://www.loci.wisc.edu/ome/formats-download.html

Download the loci tools.jar file

Then copy this file to the imagej plugins folder on your hard disk.  
Restart imageJ, then Go to Plugins>LOCI>Bio formats importer in imageJ.

Not sure how well it works will liff files but i'm sure it will allow 
you to view your data and possibly save in other formats.

cheers,

Matt.
