[SOLVED] [Ionic-v4] Best way to faster download images and display responsive, in ionic

#1

I would like to fast download these objects in my ionic 4 app and display the image.

1- I do that with the http client in ionic. I can get my data and display images but the download is too slow because of images.

2- And when i display that, they are not responsive although I use grid. No problem In browser, only in android device.

I use Ionic 4, my Backend is base on spring boot.

Hope i will get help or orientation.

Thanks
Best regards.
