Assuming the context menu only shows for jpegs (.jpg and .jpeg, i.e. we don't need to put the word "photo" or "picture" in the text to explain what we're geolocating),
The context menu will show for all types of files since other image types besides jpegs can contain EXIF data.
then simply "Geolocate" would be enough.
Sounds good to me.
I don't expect the right-click menu to know in advance whether an image has a geo tag or not, that's too fancy and I doubt it's even possible.
Correct, I can't know in advance without scanning the file.
If there's no latlon info in the file, will you be putting up an error box, or just bringing up a map with no pointers placed? (If there's a choice I think I'd prefer an error box but whatever is easiest...)
The app traps for the complete lack of EXIF data as well as the lack of GPS data within existing EXIF data. A typical message box is shown and the app exits after the user clicks okay. Cool?
