Image not centered on gallery

Hi,

Please note that you can use Mosaic or Masonry views in order to display images with their full width and height, however, these options are available in the Premium version.

Otherwise, you can crop the images. Please go to a Gallery > there is a Crop tool below of each image and crop the image with your desired dimensions. Check the gif.

Lastly, you can increase the dimensions of the Thumbnails from the shortcode options when inserting the shortcode into a page/post.

Please let me know if the information helps.

Thank you!

Have a nice day!
