Digikam is currently released as a snap using this Snapcraft project. One of the features of the tool is to easily manage your photos from your camera for culling and/or importing.
To make that task easier, I am requesting autoconnection for:
udisks2 for storage device enumeration
removable-media for mounting (sdcards or camera-as-storage)
mount-observe for digikam to check if the destination has enough storage space to hold the imported media
