How to replace vertical photos with horizontal ones

[flwolf]

I've tried to utilize the "Photo Gallery" page 6 template, but there are some vertical (portrait) photos, and all my pics are horizontal (landscape). I've tried cloning a pic, but then the same pics show up in both.

I think you need to spend a bit more time with the application and help file before posting trivial questions at TG. It's all in the Help file
Also, the search function at the top right of each page here gives excellent results for these FAQs.
