This is a test using the latest version of the WordPress iOS app.
There are two problems with the iOS app as far as I can see. One is the size of the uploaded image, which is 205kB. The other is minor, but it’s the strange and meaningless name of the image, which is 20140528-175753-64673987.jpg
Had I used the browser to post the image, I would have been able to use Photoshop and the Save-For-Web feature and the image would have been around 50kB.
