I’m a new theme author and currently preparing my preview images. I’m a bit confused about the image sizes I’m allowed to upload.
I read the following in this help guide:
Preview Image Set
You can provide additional preview images. They must be JPGs no larger than 900x900px , and named in the order that you want them to appear using the following format:
01_preview1.jpg, 02_preview2.jpg, 03_closeup.jpg .
Create a .zip folder containing your additional preview images.
Is it correct that I may upload as many images as I like, but with a maximum dimension of 900x900px and that those images show below each other?
But how is that done with the resolution? 900px is not really big. And when I view a theme on Themeforest, open up the browser inspector I see images with dimensions like 2200 x 5000px high. Can anyone explain to me how this works?
