There are images in Wikipedia articles. If I click and image a kind of "fullscrren gallery preview" opens as HTML overlay. There is an image description at the bottom of the page (above author) in classic website but the mobile website lacks the description. This sucks as for example the image caption of image gallery (<gallery>) goes to this field which is missing.
Solution: Put image caption to mobile website too.

image caption missing in mobile website
image caption present in normal website (market in red)
