We're aware of the photo upload issue and are actively looking into it. We're working to get it resolved as quickly as we can, but in the meantime it appears to help if you have the option of uploading the photo from a faster connection (if you happened to be using public WiFi or a cell network). We appreciate your feedback and patience.
We believe we've resolved the photo upload issue—our tests indicate that the requests are no longer timing out. We're still keeping our eyes on things but feel free to let us know if you experience any further issues.
