Uploaded image not showing fully, only part of image is shown when clicked on it.

Earlier it was okay but now, recent updates has destroyed the form. When entry is submitted by the form. We click on image to see at large but, it fills the whole screen and only part of image is shown (specially portrait mode). There is not option to drag the image too. How can one see the image without downloading. Earlier when we click on the image full image was shown. But now only part of it is showing. Very frustrating experience. Please solve the issue URGENTLY otherwise we will go to other service provider.
