On the main gallery page, the one that shows all the thumbnails (small versions of each photo), the size of the thumbnails depends on the width of your screen or window; the wider the screen (or window) the bigger the thumbnails. If you have a smartphone, you can turn it sideways to have a wider screen.
To see all the photos in the gallery, click on the first (or other desired) image and then keep clicking on the first triangle. OR... just click on the images themselves, which does the same thing.
When you are in a sub-page, the image always adjusts to fit your screen, no matter if you are using a cell phone, a tablet, or PC (but the maximum image width is 720px). If you want to see the full-size image, click on the button next to the triangles, then use your browser's Back button to return to the sub-page. When you click the Enlarge button, the way the full-size image is displayed depends on your browser. If your browser scales the big image to fit your screen, you should be able to click the image to see it full size (i.e. bigger than your screen, in which case you have scroll around to see different parts of it).
Most sub-pages have a caption below the image. If the image is taller than your screen, scroll down to see the caption. Or on a large screen, you can also make your browser window narrow; this reduces the image size, bringing the caption into view.
