I found a cool spider

I found this cool spider at my grandmas and put him in my 36x12x18 glass terrarium so i could watch him and his actions, he's made some streams of web but not a whole one and I was wondering if anyone knows what kind of spider she may be, he has fangs, awesome markings, and his body is about an inch long and his legs add about an inch also, thanks

Some pics would be helpful.

 

lol ok, I'll try and get some up

 

my guess is a weaver spider or something like that. i've been around bugs my whole life and my dad always identifies them. so good like. and don't forget to put some crix or flies in there with it.

 

I let her go, and named her Shelob after the spider in LOTR
