I'm sure it does, I have no involvement with the development of this forum, I am merely a mod.
I've used Techpowerup.org to upload images, then copy and paste the code into my posts for over a decade now. That's all I was suggesting as an option that should still work great. Many folks use a different third party image hosting solution on this forum, before Xenforo 2.0 when TPU had one all along that is actually pretty awesome. That's all I was saying. I'm not complaining, as it saves a step, just pointing out the old way is either broken or superfluous.
