Bulk upload photos to activities

Roughly how many files are you talking about?

Well, I have training data from middle 80's and forward. So if possible to bulk upload, many, many hundreds of photos.

Are you familiar with the use of the Ctrl and Shift keys for moving multiple files in Windows?  I don't know your skill level within Windows but you might be able to use the Ctrl and Shift keys to copy the files, then once you are sure they are in the desired destination, delete them from the original source.  As an example, lets say I have 20 files in a given location and I want to make of copy of the first 15 at some other location. Select the first file, hold down the Shift key, and click on the 15th file. Then right click the selected list of 15 files, and select in the normal manner Copy >> Paste (at the desired destination).  The Ctril key allows some selectivity, say you have that list of 15 files selected, but you decided you don't want file #9 and #13. Hold down the Ctrl key while clicking on #9 and #13. They will be deselected. Then do the Copy >> Paste operation on the list.

How would that upload a photo to a specific activity in Garmin?

Aren’t you essentially moving files from one location to another?

Anyone knows if it would be possible to script upload these photos somehow?

Sure, if you are a JavaScript coder or hire one, it can be done, though it will not be a trivial task for half an hour, especially if you never tried coding anything for Garmin Connect. Anyway, you would also need to have a database or a naming pattern for the photos allowing to associate the photos to their respective activities.

I'm quite aware of the things you are mentioning. Since it obviously is not a trivial task I'm asking here if anyone has done it before.

I doubt, because TBH preparing the database associating the photos to their respective activities will probably take you similar time to the time needed for the manual upload, unless the association can be automated easily, for example by using time stamps.

The association of photos to an activity id is not a problem, the question is if it is possible to do a bulk upload...
