It is not possible to insert multiple image files in writer and calc from going to option Insert --> Image. We can only insert image one at a time. We need to have option to select multiple images by pressing ctrl+ click on mouse for required images. This is a very important enchancement required in Libre office as most of the users use to insert multiple images to insert a picture for each item description or any other purpose.
Please do the needful to fix this bug.
