So if you’re silly like I am, here is how to upload a gif to add for that ‘extra effect’ in your post.
Save your gif to your desktop
Go into ‘Add new post page’ and click the upload/ insert button above the text toolbar
Make sure you have uploaded the right gif and to make sure the gif works and moves you need to upload the gif in it’s ‘full size’ so that the gif does not compress. If you click small or medium etc. the gif will compress and you will only see a thumbnail visual. Which you don’t want because it won’t move and you’ll be annoyed.
The gif will appear in your post square and if you have uploaded it right, which you should have because I just told you how to do it, it will be moving YAY! So all you need to do now is press PUBLISH/UPDATE
And now it works hurrah!!!!
