Hi all. While I understand why you are approaching things this way, I am not sure it is the best thing to do. It's good to see that you're using Wikidata as part of the input for these suggestions, but a lot of Wikipedias now are heading towards using P18 values directly in infoboxes (e.g., on enwp, telescope articles already do that; lots of eswp and frwp articles also do so; and of course Commons infoboxes display everything from Wikidata).
I suggest instead to focus on adding P18 values to Wikidata items - and to also think about adding other image values, like P3451 (nighttime view), there are also interior views, coats of arms, etc. That way, you will significantly increase the impact of what you're doing (the images will be used in multiple languages from the start), while avoiding adding extra clutter (when converting an infobox to Wikidata, do you use the existing image on Wikidata or the one from the article), and you're more aligned with what others in the community are trying to do (expand Wikidata and increase its usage), while your current approach may easily bring you into conflict with editors on the different Wikipedias.
(Also, note that P373 will hopefully be deprecated soon, you're best using the sitelinks to Commons instead.)
