**Benefits:** Lets users to quickly open multiple reference images at once.
**Description:** Currently Blender supports accessing multiple files at once, but the image-open operator only supports loading a single image.
This patch would load all selected images, presenting the last selected file as active in the image view.
**Challenges:** Supporting loading from the list of files as well as the active (last selected file), without loading duplicates.
**Hint:** See the sequencers **Add Image** operator for reference.
