Hi,
asuming that there is extractable text with-in the eps files, you could
try adding the PSPlug to your collect.cfg file. By default the plugin
looks for files that end in ".ps", so you can either manually rename
your files, or add the following option in the collect.cfg file:
plugin PSPlug -process_exp "\.e?ps"

This will tell PSPlug to process files that contain either ".ps" or ".eps"
If you add a '$' to the end:
plugin PSPlug -process_exp "\.e?ps$"
then the filename must end in that, not just contain it.

Hope this helps
