Make the Share function Detect picture from the URL and offer share options accordingly.
add Instagram or similar apps to the share option when the URL ends with .jpg or .png or any other supported format so that the share function will detect it's a picture and will offer installed Instagram app or others as a share destination.
it already happens when viewing a picture in Windows 10's Photos app.
options with the red lines are only available in Photos app, they should be available in Edge browser too when viewing a picture And the URL ends with a supported picture format like (jpeg, jpg, png etc)
Note that the list can contain thousands of other apps that only work with picture.
