This is a feature for [[https://www.wikidata.org/wiki/Help:Data_type#Commons_media|Commons_media datatype]] on Wikidata.org:
**Feature summary** (what you would like to be able to do):
If a Commons file has several pages (e.g. a djvu or pdf), the thumbnail is currently generated from page 1. This can be relevant or just a mostly blank cover sheet.
Sample: https://www.wikidata.org/wiki/Q75803176#P996
Wikidata uses the [[https://www.wikidata.org/wiki/Property:P7668|qualifier "file page" number (P7668)]] to indicate which page should be displayed. There is also the [[https://www.wikidata.org/wiki/Property:P4714|qualifier "title page number" (P4714)]] for other cases. If both are present, P7668 should be used.
