Prestashop Header

[LicoriceLabel]

Hi im not sure if im posting in the right section here but i was wondering is it possible to add page with a photo gallery in the header. i would like to add the page next to where the tshirts section is in this page http://dgcraft.free.fr/urban/ i am using an edited version of this theme however its offline at the moment.
i understand to add a page in the header you have to use the catalog in the back office however this only lets me add products and i wish just to add a photo page.

Could somone please reply A.S.A.P

Thanks
