An improvement you can make: instead of using filterBtn[0] to set the click event listener, you should check the ID of the button element to get the type. Otherwise, if the order of the buttons gets changed, you wouldn't need to updated each of the click event functions. This would also allow you to have cleaner code, because you could create a more generic click event listener for all the buttons using a for loop.

selectFilter = 'All';
displayPhoto();
};

filterBtn[1].onclick = function() {
selectFilter = 'Nature';
initialPhoto = 6;
displayPhoto();
};

filterBtn[2].onclick = function() {
selectFilter = 'City';
initialPhoto = 6;
displayPhoto();
};

filterBtn[3].onclick = function() {
selectFilter = 'Animals';
initialPhoto = 6;
displayPhoto();
};

displayPhoto();
