Occasionally I wish to upload a picture into what I am posting, and I believe the systems intends me to be able to do that.

I click on 'insert image', and a dialogue box comes up asking if I want to post it from my computer or from a URL. I click on 'computer' and then click on 'select file'. Then I get a to select the location on my computer. I select the file I want and then click 'upload file'.

Then I see a progress bar while the file uploads.

Then what am I supposed to do? If I close the box the system forgets about the picture.
