ok so for that you need the bb codes (I think that's what they're called)
so for images/gifs you need a link to the image or gif, then you need these codes: [image] and [/image]
for example, I have an image I wanna put, and this is the link to it:
https://ca-times.brightspotcdn.com/dims ... te-pup.jpg (MAKE SURE IT HAS THE .JPG OR WHATEVER THE END IS (Can be .webp or .jfg or .gif))
then im going to put [img](link%20here)[/img]
And it should come out like this!
