The Photo Galleries web page opens with a view of photo albums arranged by year of the event (for example “2018 Photos”) with a snapshot/thumbnail from each collection, or “Gallery” of photos for that year.
.
When you click on one of those photo galleries (e.g. 2018 Beginners Tournament) you are taken to that “Gallery” of photos.
The basic view of each gallery has small images of each photo, these are known as “thumbnails” and are decent size to view.   But if you want to see the photos in full-size just click on any thumbnail and a full-screen slideshow will open up.  The slideshow will show all the photos automatically, but you can pause the play by leaving the cursor on top of any photo, and then restart by moving the cursor off of the photo.  You can also advance the slides forward or backward by clicking on the small triangular icons to the right and left of the photo.  To exit the slideshow just click the “x” in the upper right corner of the photo (or you can enter “esc” on your keyboard twice
If you are viewing the slideshow on your smartphone or tablet you can close the window by “swiping up” on your phone/tablet.
To download or print photos there are three options – in the “gallery” view there is 1) a link at the bottom of the page to download the entire gallery, and 2) if you put (“hover”) the cursor over a photo without clicking it, both download and print  icons will appear and if you click on the icon then that single photo will be downloaded or printed to your computer; and finally 3) in the slideshow view – if you put the cursor on any image a download and a print icon will appear and if you click on that icon then just that one photo will be downloaded or printed.
