Attach custom gallery to a page

I am developing my first WordPress website and am trying to find a way to do the following. Website editor needs to be able to create image gallery pages by attaching multiple images with metadata when creating a new page. For each gallery image there are full size and thumbnail images as well as image description. I would like to use some plugin similar to NextGen gallery to manage picture libraries in WordPress but i don’t want this plugin to actually display any pictures – I have a custom made jQuery gallery for this. My html code will have to be produced by a custom page template.

So, I am looking for either a plugin which would allow me to “attach” grouped custom fields to a page (images or image URLs and descriptions), or may be a direction how to customize a plugin like NextGen Gallery so that it didn’t add any of it’s code to my pages.

Also, possibly please consider that I am not a PHP dev and I won’t be able to do difficult code customizations without good guidance.

Many thanks for any help.

You can upload images in media of each page by using INSER GALLERY button.You can Upload multiple images & galleries also.

You can get all images of each page by using below code.

$images = get_posts(
    array(
         'numberposts' => -1,
         'post_parent' => $post->ID,
         'post_status' => 'inherit',
         'post_type' => 'attachment',
         'post_mime_type' => 'image',
         'order' => 'ASC',
         'orderby' => 'menu_order'
         )
);
