Hi,
I see a syntax typo I like to report.
When an image inside an article is clicked to see a larger size (NOT in Media Viewer Mode), a page will be opened with the image filename after File word before it, below image is displayed. The matter I want to point is after File word and before media's filename, there is a colon ( : ), regarding many articles on net (including Wikipedia itself) it's better/should be a space after a colon, but in this case there is no space before media's filename and after colon.
I think its better to be considered if I'm right about it.
Wikipedia - Colon
StackExchange - Spaces around a colon
Wikimania - Colon: Space after not before
