Loading url images from firebase and cloning buttons

Hi! Please could you help me with this blocks? the first time I load them, everything is fine. But if I navigate to this screen more times, starts to crashing or navigating slowly.
the images weigh is 483 kb.

Can you give me some tip? or Other way to configure the blocks? Thanks you very much
