Is there some app that takes multiple images and generates QR code, and of course that it can also do reverse so you can scan QR code and view images.

QR code should contain images, not link to images.

I don't think that will work. Even a small jpg with under 1mb has to much data to get in one QR code. Not even considering multiple images. You probable can get one small svg icon into a QR code... but what's the use case anyway?

Yeah, I was thinking it would be hard to store that amount of data in QR code even if image quality was reduced.

My cousin had an idea to make (print) an album but wanted to do it with QR codes because it would be cheaper to print (only black and white printing is required).

More data makes qr dots smaller and smaller. Then you have to throw in error correction and you quickly find that they become unreadable fast.
