There's also the Lois and Clark Archive and Bananna\'s Followtomorrow.net site.

Both have a good collection of screen caps, though the archive one has all the eps and the average per ep is higher [but I have found the split second I wanted on one site and not the other before so definitely worth looking at both if you want a specific shot]. The archive also has a bunch of archival footage like videos and stuff [though not all of those links work frown ].
