I was looking at some old threads and now I found out that they are putting some images under their replies. Can anyone explain how do I add these? Sorry I wasn't so active in this forum.
That's called their signature! If you click onto your username in the top right corner a little dropdown menu will appear and you'll see the word "signature" that you can click. That'll bring you to a page where you can upload a picture to use as your signature! With the signatures though there is a size requirement - it'll automatically set it's own width but it can't be any taller than 250 pixels. You'll be able to adjust the height of your picture once it's attached and such.
Hopefully this makes sense! If it's confusing let me know and I'll try to attach some pictures.
There's also this handy Signature Guide that might help! It even has a picture that shows what your signature should fit. I still always need help with mine lol
