Adding 406,000 photos, 400 galleries and 280GB. Best Method?

I have over 400 different galleries with over 406,000 photos and over 280GB in size (football games).

What is the best method to add these to my website?

Each page will have one gallery, on average 1000 photos per gallery. The most one gallery holds is 2000 and the least would be 100.

Will I need to use an outside app in order to showcase these?

Will the storage space be an issue? Will I need to batch process the photos in photoshop to reduce storage space so I don't hit any limits (are there storage limits?)

Thanks in advance for any help and suggestions -

You’ll need to use an alternative platform. Squarespace Gallery pages and Gallery sections are limited to 200 images each. 

If you are building a site for a photographer to share, deliver, proof or sell images online, you may want to consider Pixieset.
