Reason 1, a Tall/Wide Image
When a gallery is displayed, the component works out the height of the tallest image in the gallery, and works out the width of the widest image.
The gallery then sets the width of the main image container to the widest width, and the height of the container to the tallest image in the gallery.
The component then injects each image inside the image container, centering it vertically and horizontally.
If you gallery has 10 images that are 400 pixels high, and one image that is 700 pixels high, then image container will get set to 700 pixels, and all the 400 pixel high images will have white space above and below them.
The gallery does not change the size of the main image container when the image size changes. If it did, the thumbnails/ descriptions/ content below the picture would jump up and down when the image changes, which is very distracting
Reason 2, empty image descriptions
In the profile, in the "Other" tabs, you can set whether the image description displays, and how tall it is. If the image description is set to below, with a height of 50 pixels, and you have no image descriptions, there will be 50 pixels of white space below. If this is the case, you can turn the image descriptions off in the profile.
Reason 3, category description has white space
It may be the case you have given the category a description, and in the profile - "main other tab", the "Category Description Position" is set to above. The category description may have some extra line breaks or empty paragraphs in it. To check this, please click on the category name, and choose the html button on the Joomla editor, to check if there is any extra line breaks or paragraphs at the bottom.
