Hi Stefan,
I add sometimes image tag during surveys. For example, I added yesterday the tourism=picnic_site at the Bois de Jussy: https://www.openstreetmap.org/node/7143286065
And as you can see I also added the image tag to this node: image=https://commons.wikimedia.org/wiki/Category:Bois_de_Jussy#/media/File:Picnic...
The same for the model aircraft aerodrome, which I also discovered yesterday: https://www.openstreetmap.org/relation/5960286
I carry with me a quality portable photo-camera on surveys specially for making such images. A good photo with the GPS coordinates in its EXIF properties removes any doubt that a picnic site or a model aircraft aerodrome exists in this place.
Adding the image in this format: https://commons.wikimedia.org/wiki/Category:Jussy_Modele_Club#/media/File:Ju... allows a mapper to see other images of this object in the Wikimedia category immediately, i.e. to view the object from different angles, and by this to understand better its location.
Since these are the HD photos, an experienced mapper could notice some details, which the original author missed, and to add them on the map too.
Best regards, Oleksiy

I've made a query on my local PG/PostGIS database os OSM Switzerland loaded using osm2pgsql (I call it EOSMDBOne). There I can do queries like "SELECT count(*) FROM osm_point WHERE (tags->'image') ilike 'File:%';"
The total osm_points with image tag was 1212. The majority of image tag values contains 'https://commons.wikimedia.org/wiki/File:...', namely 849. I only found 38 image tags with a value beginning with 'File:'. Tag wikimedia_commons occurs 293 times in osm_points of my db (which is close to taginfo.osm.ch).
So to me that's now a dilemma is to choose between the key "image" with value https://commons.wikimedia.org/wiki/File:...' versus the key "wikimedia_commons" with values either "File:..." or "Category:...".
As a consumer of OSM data I would document and implement both for now.
In any case the wiki page about image [1] is outdated regarding "formatted as File:image.jpg" when saying
a Wikimedia Commons filename (formatted as File:image.jpg) - although this is commonly tagged as wikimedia_commons=*

Hi Andreas,
One more piece of information which you may or may not know or not even be interested in ::
The d/d5 in the second two urls is the first and second alphanumeric characters of the md5 hash code of "Drinking_fountain_in_Palmerston_North.jpg" (without the quotes).
Best regards,

Hello,
I have noticed that the links to images in wikimedia commons for fountain nodes ( but I assume it is the same for other nodes, ways and relations) are sometimes saved as the page url, sometimes as the file url and sometimes as a thumbnail image url.
Would it make sense for someone to run a bot and convert all wikimedia commons image links to the root image link? Especially the thumbnail image links .. maybe it's not such a big deal.
For example,
https://www.openstreetmap.org/node/6465995645 has image link https://commons.wikimedia.org/wiki/File:Drinking_fountain_in_Palmerston_Nort...
https://www.openstreetmap.org/node/6431460585 has image link https://upload.wikimedia.org/wikipedia/commons/5/5c/Israel_Hiking_Map_%D7%91...
https://www.openstreetmap.org/node/286879718 has image link https://upload.wikimedia.org/wikipedia/commons/thumb/8/86/House_%26_square_o...
Which one is the "root image" link?
cheeers, h.
