Is there a site that has all or most spider names with photos?

Question

Not one in which you need the spider's name.

Answer 1

Try starting here:
http://www.arachnology.org/
Click Arachno Web on the left -- or search around on your own there.

This site also has links to others that might be useful:
http://www.entomology.cornell.edu/Faculty_Staff/Rayor/Spiders/Resources/Spider_Identification.shtml

Finally, this may be the one you really need -- seems to START with photos: http://lancaster.unl.edu/enviro/pest/SpiderPhoto.htm
