Map changes zoom level when selecting a new image about geotagninja HOT 4 CLOSED

Hi,

I'm not sure this is fixable as such. The map itself is very independent of the app, it's a leaflet-based add-in -> https://leafletjs.com/

Here's the issue: when the user clicks on an image the app tries to estimate the relevant area for the image on the map and then puts the image on the map with the coordinates +/- some area. This is so that 1) we are not showing the whole globe literally and 2) we are showing the area where the image coordinates are. In reality this is particularly important when the user selects more than 1 image so that the markers are all showing properly on the map in a way that's kinda "neither too small nor too big".

From a coding logic the way this works is that when the user clicks on any number of images the map is reset, then for each of the coordinate pairs in the clicked-image-list we record those coordinates someplace and then calculate the extremes of the coordinates to form an area to show. This is largely because if the user was to unselect one image out of the possibly many selected it's a lot easier to redraw the whole thing than to attempt to find a marker on the map (reasoning being is that markers are not named entities and if user has more than 1 selected then it becomes impossible to "undo" one particular marker)

So when user select a different image, even one with identical coordinates to the previous the area box coordinates that get sent to the map are reset and the marker for the image gets put on the map.

Admittedly at the moment I'm not sure how to read the zoom level from the map without it being clicked anywhere, but that's relatively irrelevant in the big scheme of things because in map.html the fitBounds code logic defines where to point, which as per documentation comes only with the maxZoom option, which is already being used so a zoom-per-se can't be enforced (and would not be possible either as per above explanation).

Just guessing, could this be depending on the coordinates. I'm trying to geotag images in Lisbon, ~9 deg West, so could the negative longitude cause issues.

The zoom always resets regardless of East or West orientation because when you click on 1 or more image the app calculates a coordinate box/area to show all of the coordinate markers on the map and that sets the view.
You can try the Development version as I did poke around with negative coordinates in it a while ago (in particular regarding showing them on the map) tho I think that change is already in the Main branch too.

The development version I downloaded from the Google Drive works correctly.
