Do you know what is causing this? I've tried about ten times in a row to upload an image that is well within the file specifications. Tried waiting a few minutes and same thing.

The uploading completes fine (the little gray progress bar finishes), so I click the "Save" button to make the post, and then it keeps saying "Posts must be an image, text, or link." Usually when it does that you can just click "Save" again and it will complete the post successfully, but right now it's changing to "Network error." which I have never had happen before.

In general "Image Post" is pretty flaky, usually taking about 2 or 3 tries, but eventually it works. Usually when it doesn't work, it pops up that white "X" over the image, but this time it's just making the image disappear, as if you didn't just upload it.
