Is it possible change gallery miniatures in a portrait size instead of landscape

Hey JoStudioDeRijp,

Thank you for the inquiry.

The thumbnail size can be set in the Gallery’s Styling > Gallery Preview Image Size settings. Try to set it to the first option if you want to display the original size of the images.

You could also use the following plugin if you need to adjust the size of the registered thumbnails.

Hi,

When I choose for example Portfolio 495 x 400, all the miniatures are shown in that size, even if my images I set in the Media Library are all different sizes.

That is how selecting a thumbnail is supposed to work, so it is actually recommended to upload images with the same size. Another solution is to use the original image and show it as is, or register another thumbnail or size as you see fit and use it instead.

// https://developer.wordpress.org/reference/hooks/image_size_names_choose/

You can use the add+image_size function to register your own thumbnail or image size, and the filter image_size_names_choose should allow you to include the new thumbnail or image size in the image list so that they can be selected later on.

Best regards,
Ismael
