Gallery image size differences

Dear support team,

I want to add new images to my gallery, however when I add new images, they have totally different sizes (smaller, scroll down in the gallery). Link: The first batch of images that I uploaded were not sized identically but WordPress shows them in the same format, why does this not happen when I upload new images?

How can I make sure the images are shown in the same format? I’d like the edges to connect like the first set of images are currently. The others are showing white spaces in between.

Thank you.

Hello Marcel,

I suggest you to use either portrait or landscape orientation images, not both at the same time. Also please make sure that you upload at least images of the same aspect ratio.

Please feel free to ask any other questions that you might have.

Kind Regards, Roman.
