Any good Android Apps to showcase photos to clients?

[vadim2200]

I am a wedding photographer and am looking for any good android apps that I can put on my tablet to showcase photos to my clients. I would like an app that can showcase photos in Collage format (multiple photos on a single page). With many any apps and photo galleries just have an option to scroll with single image, one at a time. Can someone suggest something? I stopped bringing photo albums long time ago and find tablet much easier
Thanks
