If you want to download everything under example.com/main/eschool/PhotoAlbum/Album/ but not above it, you can use the --recursive and --no-parent options:
wget --no-parent --recursive http://example.com/main/eschool/PhotoAlbum/Album/
This will load everything below the Album directory. If you want to limit the depth of diving wget into subdirectories, you can specify the --level option:
wget --no-parent --recursive --level=3 http://example.com/main/eschool/PhotoAlbum/Album/
This will expand to 3 subdirectories below Album .
However, none of these methods filters by name - they will blindly load everything into the directory and its subdirectories. If you need more control (for example, to download albums starting with 20* ), you will have to use a script shell or scripting language.
