This is all true IF you have the image already loaded somewhere on the web. That takes few more keystrokes than three.
Other sites I belong to allow direct downloading and storage to the forum. No third party hosting required.
Please correct me if I'm wrong.
Slobodan is correct, you can upload directly.
The two problems are that the default is to link to another site, many clicks in the process, so much preperation.
The other is that you can choose, "Attachments and other options" and then click on "Attach". So intuitive, not.
There are approximately 1.8 billion images uploaded to the web each day. LuLa with around a dozen or so images uploaded each day needs to catch up…
Cheers,
