Hi, There appears to be a change in the way en wikipedia handles the image: page of an image that's hosted on commons.
Until very recently (today?) viewing such an image page showed the "this page does not exist" stuff, but did contain a link to the corresponding image page on commons. Now the text "This file is a shared upload and may be used by other projects." appears, and there's no link to the commons page.
As one can't easily see the source or licence info for a commons image anymore (cut'n'paste is required now), this is somewhat suboptimal.
