So, you wanna upload a image or a Gif, I’ve seen a lot of people ask so here is a tutorial.
For images
Use Gifyu, you don’t need an account and you just put this:  and you are done!
For Gifs
Use giphy, You need to make an account, set the Gif to public and copy the link and do the same thing you do for images:  And that’s how you do it!
And to prove it I’ll put an image and a Gif
Right under here
WAAAIT!!!
To get it to work, you have to hold the image and click open in new tab.
And for Gifs you have to click open image in new tab for some reason
