This question is an exact duplicate of:
Is it possible to add Wikimedia Commons images in the questions/answers without uploading them on imgur? Since the images on Wikimedia Commons are free, it's a waste of hard drive space to upload them on imgur just to be able to show them in a SE question. I've recently asked a question where I provided links to two Wikimedia Commons images but I would prefer to directly include them in the question - without uploading them on imgur.
If not, then I would like to place a feature request to allow this.
