Hi,
1.Go to media library
2.Pick the image you want to edit
3.Click in “edit more details” which should be to the right of the screen under “copy url”
4.This should take you to “edit media” page; look at the top right of the screen next to help and you will see SCREEN OPTIONS. Click on that.
5.You will see a list of options. Under “boxes” select “SLUGS”; you should see a tick in the box.
6. Scroll back down to the bottom of the page under the image. Right at the bottom you will see a new field “slug”. The current name of your image will be written in that box. You can then change the name to whatever you want.
7. Under “save” click “update”.
8. You now have a new permalink with the name you have just picked. Ie https://mywebsite/name-of-image-i-have-just-changed
(Please note that as far as I know this only works if your permalinks are set to “post name”. To change to this go to Dashboard/Settings/Permalinks. Once on that page select “post name” under common settings.
This is a serious change as it affects all your permalinks on your website do it with some thought)
