simple but annoying fix that i need help with????

http://www.everythingtonothing.com/gallery/ <---gallery link

can someone tell me how to get rid of the colored link border around the image at the top of my gallery? i believe it is the a:link type thing but i looked everywhere and can't seem to find where the style is to get rid of it.

also how can i center the "gallery version" at the bottom, couldn't figure that out either.

i know these are small but your help would be greatful.
thanks,
mike
