This is a test. Uploading works by dragging the image from your explorer window and dropping it into the post dialogue window. Can't say if I am just lucky or if it works for everyone again.
The "classic" picture upload procedure by opening the dialogue box and chosing the image file is not working (yet).
I also use Chrome, and worked for me, I posted this morning using classic upload method. Perhaps it works intermittently, or it's a provider related issue? I don't think the problem is browser related...
