Working on the magazine advert

I have now taken the picture of the members of the band there are going to be included on the magazine advert for the album. I have imported these pictures into Adobe Photoshop, created a border to make them look like they have been taken on film and put a black and white filter on them. This makes them not suitable for the magazine advert. Now I need to add these pictures to the rest of the advert on a separate Photoshop file and assemble it with rest of the thing that are going to be included on the magazine advert.
