Definition: In Greek, "gallery" refers to a collection, usually with many pieces, but in English, it's used for pictures or photos, making it a broad term. The word "gallery.php," in this context, seems like an application where multiple pages with gallery content are displayed. The definition of "gallery" involves multiple images, possibly with the same image repeated several times (which would be in "gallery.html"), often with different variations (e.g., zoomed-in versions). If I understand correctly, a 'gallery.php' typically contains HTML and PHP code to generate an array of images and display them on a webpage. This can include a grid of thumbnails or gallery-like layouts where the user can click each thumbnail to view more details about it. So in essence, "gallery" seems like a broader term that encompasses multiple pages with related content from various sources.
