Help to save more images on fire base

Hy there i need to save on fire base about 30 images for an app a part for the client where i need to see the images and a part for the "server " where i need to add images. I come out with this code to save only 1 image:

But i need to save more of then (30 specifically) how do i do it? I need to have x30 KIO4_Base641 or how can i do it?
Eventually i can save 3 of then at time (With button1 i save images 1, 2, 3; With button2 i save images 4, 5, 6)

My advice is to use Firebase Storage:

Mhm ok i was thinking to use classic blocks of fire base because its more simple firs, second the page have already 1600 blocks on it and as i seed its more longer of classics blocks (LOL it takes 6sec to load the blocs page and interact with an item :joy: :joy:) and 3 i don't get exactly how to use web links to that purpose...

The method I showed only uses "classic" blocks, as you put it. Your approach requires an extension. The method is fully explained and demonstrated in the link I provided.

Do you think i can use another screen to save immages? At the moment i am using only 2 pages

Not necessary, but you could.
