Photo Collage

Hi

I need 9 celebrities in the photos in the link to be collaged into 1 big photo

Its for a presentation and the aspect should be similar to a powerpoint presentation

https://www.dropbox.com/s/j9355rzsxbc6v79/Photoshop.zip

There is 10 photos in the zip file, 2 are of Niall Horan, please choose one that suits

This should be straightforward for a photoshop expert.

Quick turnaround time is necessary

Regards,
Fab
