Repeat list takes too much ram

I use a infinate list in a page, each item has a image and each image is more than 100KB.So there is a problem, when I scroll serveral times, these items with image takes too much ram(less than 100 items take more than 120MB!).
Does ionic or angularjs have a way to make it possible that when scolling out of device view,these image are removed from the page(like native app) and when scrolling in , these reload again?
