Change the way IHM-uploaded images are tagged in OSM

[zstadler]

What is the problem this feature will solve?

Currently, IHM-uploaded images have a hard-coded full URL in the OSM image* tags. This requires IHM software to find an use that URL given the image name that was uploaded to Wikimedia commons

What is the feature you are proposing to solve the problem?

According to the OSM Wiki on Photo linking, there is another way to link to Wikimedia Commons image - the wikimedia_commons key.
For example: wikimedia_commons=File:Eiffelturm.JPG.
When there are several images, a Wikimedia Commons Category can be used: wikimedia_commons=Category:Eiffel Tower

Access to the image can be done using hotlinking based on the file name. For example:
https://commons.wikimedia.org/w/index.php?title=Special:Redirect/file/Eiffelturm.JPG
https://commons.wikimedia.org/w/index.php?title=Special:Redirect/file/Eiffelturm.JPG&width=300

What alternatives have you considered or tried?

Keep the system as-is

When there are several images, a Wikimedia Commons Category can be used: wikimedia_commons=Category:Eiffel Tower

Who will create these categories? What happens to places that don't have a name?

Besides the above, there's a need to open a bulk edit announcement in the OSM forum.

I'm good with this idea as long as we solve the above issues.

Who will create these categories?

If we can do that through the API, and if it would simplify the handling of multiple images, we may create the categories ourselves. BTW, there is already a Category:Israel Hiking Map

What happens to places that don't have a name?

I believe there is already a mechanism that sets the image names. That need not change.
For example: File: IHM Cave*

Besides the above, there's a need to open a bulk edit announcement in the OSM forum.

IMHO, this is optional, assuming we will want to continue and use image* tags that were or will be added to OSM by means other than IHM.

This is already supported for image*=File:xxx.png as can be seen here:

Site/IsraelHiking.Web/src/application/services/resources.service.ts

Line 1006 in b919bb3

return `https://commons.wikimedia.org/w/index.php?title=Special:Redirect/file/${imageUrl.replace("File:", "")}&width=${size}`;

We use it for image caching here too:

Site/IsraelHiking.API/Executors/ImagesUrlsStorageExecutor.cs

Line 78 in b919bb3

fullImage = $"https://commons.wikimedia.org/w/index.php?title=Special:Redirect/file/{imageUrl.Replace("File:", "")}";

There is currently no support for wikimedia_commons though...

In theory, we may remove the code that translates the file name to an image url here:

Site/IsraelHiking.DataAccess/WikimediaCommonGateway.cs

Line 115 in b919bb3

public async Task<string> GetImageUrl(string pageName)

and store the image in the wikimedia_commons tag, but if we plan to support both the "old" image tag and the new wikimedi_commons then this will only complicate the code without a significant improvement, so I'm not sure I understand the motivation behind this issue...
