trying to remove images from a slide show but do not know what plugin it uses

HI,
I'm trying to remove some images from a page on a client site. The link address is:
http://www.phaseinc.org/portfolio/paradise-estates/

I see there is a section in the admin panel called portfolio but it does not let me change the images. I'm trying to narrow down what plugin is controlling it but haven't had any luck yet.

Any help would be appreciated.
