Native App show image as full image

Hi, I have a page where I am displaying list of images as Thumbnails as show below.  Now when I click on the image I need to show it as full image. Image viewer widget available for native mobile expects width and height in pixels. I want to know is there any other way to open the image as full image without providing width and height values. I am looking for a Responsive behavior.

You could place a container around the thumbnails, and then in the onclick of that container open a page with the image at full size.
