How can I enlarge my product photos vertically?

[LaitdeSoja]

All our product photos are a little small (1x1) and we like to make it a little larger (vertically). We have reference photos if anyone can help us change our product photos.
We cannot upload JPEG here, but please let me know who can help me customize it 🙂
