Way to make a simple gallery. First, download the Image module from Durpal website. In admin/site config/, you'll find the one of "Images". Select "Image import".

Then, input the correct path which contain the pictures you wanna include in your gallery. Note the photos there will be removed away after Drupal copy them to sites/default/files/images. Press save config if ready.

Then, click "import" from the message box and you'll see a list of pictures you've just uploaded. Add title (title of the page, displayed on top of page and on browser top) and body (i.e. text below the picture)

Select the photo gallery (i.e. the album) to include all of these pages.

You can click on the links to see how the pages look.
