How do i upload a picture to a thread or comment?

you see the button next to smiles to the right, click it then get the url of the image by going to google images your image then when you click the picture click view image and copy and paste that url into the button next to smiles

 

What you need to do is to click that image thing, and when it asks for the URL, you paste the web URL of that one image, we can use imgur as an example.



The links, as you can see are on the side. I would copy+paste that link you see into that image icon you see on your tools, and then voila, the image is here.

We can use Google images as another one.

This time, I went to google, and looked up Han Solo. Now what you need to do is click one of the images, and hit the 'view image' button. Then, copy the link you see at the top.




From there, paste the link into the place where it asks you to put it when you click the image icon, then you should see your image come up. That is one way to do it, however you can also upload images/screenshots you already have using the 'Upload a File' button at the bottom. That way should be self explanatory, just select the images you want, and choose whether you want them to be thumbnails or full images.

I hope this helped.

EDIT: just saw @NotoriousRebel7474 's post. I just went a bit more in depth with explaining.
