angular - How to load all images I will use in one services? -

-

i wondering, how can load of images collection of strings, example:

['/picutre1.png','/picture2.png']

when navigating webpage displays images, user has them cached? enough make request those?

based on kind of images services return. if services can return base64 images think can store kind of cached redis or memcahced.

so in every webpages need images can set unique key bind images.

sorry bad english
