I saw a couple of questions about image posting, and wanted to add an option that works for me as of today, 9/15/2020

I use imgur.com
1) Set up a free account at imgur.com
- if you wish you can upload multiple images, sort them into albums etc.
2) When you have all the images you want to share, click on your profile name, then "generate image links" from the "view image info" dropdown, and select the images you need.
3) In the final dialog that shows up, select the "BBCode" and "large thumbnail" options. (The "large thumbnail" option will auto-resize the images to the max width supported on the forum of 640px)
(Screenshots below for this post)
Hope this helps some folk!
