I upload to imgur or
https://postimages.org
Imgur is easier but their site looks like trash now that they're trying to be a meme website lol
https://postimages.org , upload a picture, resize it if you want. I do mine around 800 width. Then click on the picture that gets uploaded. This will bring you to a new page. Then right click the image and open the image in a new tab. You should now have a tab which features nothing but the image. Get this url and post it with the image tool (with the [ IMG ] tags)
If you don't do this you'll just be posting a thumbnail of it.
In general,if you have a picture you want to share, always get the url of the direct image. Otherwise you will post the thumbnail.
