It’s very very simple.
Warning! Don’t worry. It doesn’t mean it’s a IP Tracker or some thing, I just put this warning every time I post a link.
Any use of that link is only in your responsibility and yours only!
It shouldn’t do anything. But if in any case it does. Its on you.
go to https://postimage.org (or any other image uploader for that case)
After yoy upload copy ‘Direct Link’ after you uploaded it (Scroll down a bit) and then past it in your post. Should be good to go
