How do I get white space between rows in Gallery?

[Kay11]

https://nicelymorrise.weebly.com/the-gallery.html  I can only get 3 images across one row, OK, have to accept that the white space BETWEEN IMAGES cannot be lessened, right?  But there should be white space BETWEEN ROWS and I've searched the forum and the Web without finding out how! There was white space between the rows before, but not now. Oh why?? Thank you for any help at all. At wits' end.

Open the options for the element, then go to Advanced > Image Spacing, and increase the spacing a little bit. This does add space on all four sides of the image, the increase a little bit should get more vertical space without adding too much more horizontally.

Oh thank you; it does add spacing but makes the images smaller. Is there not a perfect world? I'll work with this and the Gallery is shaping up, with thanks to all your help and tips!!
