Oh, I see what's going on here.... there are two completely different spider types, both being referred to as
"Banana Spiders":
1. Harmless Golden Silk Orb-Weavers of family Nephilidae, genus
Nephila, various species, common to North America,
and
2. Not-so-harmless Brazilian Wandering Spiders, of family Ctenidae, genus
Phoneutria, various species, native to Central and South America, which hitch a ride on actual bananas to the U.S. and elsewhere around the world.
So garlicguy, the one you have pictured is likely the harmless type #1 above, and the one you linked to is the very dangerous type #2 above.
Of course, beware the spiders on drugs:
