The comment below disappeared, so I will only post it one more time just in case it was removed for some reason and it wasn't just a glitch in the machine!.
Basically you just use this address:
https://i.imgflip.com/
then you go to the gifs page that you genetated (or another users gif on imgflip that you want to use) *only from imgflip of course!, then you add the last part of the gifs link to the end of the link above, in my case it was: 45bmxo
you can see that part of the images address taken from my generated gif here:
imgflip.com/gif/45bmxo
then you just add .gif on to the end of that or .jpg or .png if you post something other than a .gif file!, then you post it as a comment and it will then create a click to show link!.
