Does prefix 'data:image/png;base64,' of base64 affect to displaying image?

Question

I am using AngularJS. I display my image as: src="data:image/png;base64,iVBORw0KG..." successfully. When I change 'png' to jpeg, gif or jpg, nothing happened. It still displays correctly. So I want to ask you the prefix affect to displaying image or not? Negative or positive?

Moreover, I receive data image from server without any prefix. So I have to set a hardcode 'data:image/png;base64,'. This is good or bad? Could you pls help me? Thanks so much. :)

在html情况下，当您设置scr = base64String时，如果图像没有前缀，则无法正确显示。
