Search box only displays 3 items

I am using the search module in my gallery. I am wondering if there is a way to have it automatically display all the results instead of only bringing up 3 choices and then having to click on the show all button. Also, I can't seem to get the 'view these results in a slideshow button' to work at the bottom.

Any help would be appreciated. My site is www.anyeventvideo.com/events.
