Same container width & height as loaded image

I’m new to Ionic Framework / Angularjs and it is fantastic.

I’m writing and application. It requires to load images in ng-repeat list. everything is fine except image showing loading and height of container changes. I don’t want that.
I want to:
1 - keep the same height and width as loading image.
2 - show image after fully loaded (so do not show half).

more like as in Facebook App.

How can i do it in ionic/angular/css?

will be thankful if can share codes…
