Obviously, the size would still be adjusted to each device's screens. However, the extent for this proposed model would be smaller. The image still has the potential to be bigger depending on the device. In this model, adjustments to the size would only be done when:
1. The image does not fit in the UI.
2. When in Full Screen (which is itself another proposal), the image does not fit in the device's screen. For example, an SD smartphone rendering an HD image.
This proposal is tailored a bit more towards people with bigger screens looking to find details that can not be seen normally with the current model.
