So I saw in some thread that someone was having trouble with posting images through imgur and that someone said there should be a guide. So here it is.
So obviously first thing you need to do is start an account with Imgur. Then navigate to the new post button. Once I upload my image to their website I like to make it hidden to others on the site, but that decision is up to you. From there I right click on the image and open it in a new tab, then copy that web address. I then come back here and click on the little picture icon on the ribbon and paste my text into the open window. Hit insert image, and then finish up your thread. If everything worked right you will see your image show up. Good luck and I hope this helps!
edit* So there is a copy web address button that you can use on imgur, but for some reason it sometimes gives me the wrong web address sometimes. by opening the image in a new tab I avoid that issue all together. I dont know if anyone else will have that issue.
