Wordpress amendments

General information for the website: Online blog / publication
Description of requirements/features: Hey everyone,

So I have a Wordpress website, that has recently been redesigned. The design itself is fine, I just need some amendments made. www.ftpdigi.com

1) When you click on gallery images on the desktop site they open like the attached (images 1 and 2). On the old WordPress theme (Arcade Basic) it would pop out to a full screen image which looked a lot better could you see if this type of functionality could be put back.

2) Also in the old theme (Arcade Basic) you used to be able to click on the name of the author to be able to pull up all their written work on the site. It was good way of sending a portfolio of work to someone. Again it was in the old theme so I want something like that to be replicated.

3) This one is super easy. I want the font size on ALL posts (within the posts) to be bigger and the line spacing to be increased please. The current font itself fine.

The theme being used is one that was created bespoke for the site, hence the need for someone to help me do this.

Thanks

Natalie
