List of steps to reproduce (step by step, including full links if applicable):
What happens?:
In all four pages linked, an image icon along with a link in case of commons is displayed where File:Punt-construction.png should appear.
What should have happened instead?:
Thumbnails should have been shown, as for other images on the same page.
Software version (if not a Wikimedia wiki), browser information, screenshots, other information, etc:
Commons, English wikipedia, Japanese wikipedia
Further information
The file in question is one which I imported into commons yesterday from the English wikipedia, and there were no problems before importing.
Clicking on where the image should be displayed does show what should be shown i.e, an enlarged view, so its not that commons failed to receive the file data itself.
Similar issues have been reported around a week ago, and a high width:height ratio seems to be a common factor.
