Progress bar not visible
The title is self explanatory. The screenshot shows the bug in Firefox 22.0. I selected several photos for uploading, and the second one has already finished uploading, but the other are still in process and as can be seen, there is no progress bar. I also tried with Chrome 28.0, Opera 12.16 and Safari 6.0, so it's probably not browser related.
