My new framed collage of pictures

After restaurant, I thought I went to craft store and bought collage of pictures so I'd put it on the wall. I love that collage since I love all of pictures. It's better to put all 5x7 pictures in the framed collage instead of each frame. Still looking for 4 more 8x10 pictures. I want collage but all of pictures are vertical so I might buy each 8x10 frame... Any suggestion about 4 vertical pictures of collage frame?

Maybe, I buy some 8x10 frames so I'd glue them as they will be vertical.

Any Suggestion????
