BP Rental Property Tool - Pictures not working

[Curtis Hallenbeck]

I've started using the great BP Rental Property tool to analyze deals, but every time I try to add a picture of the property and click update, it stalls out.  I've tried from different browsers and computers but the same thing happens.  As long as I don't upload a picture it works fine, but I'd really like to be able to add pictures.  Any ideas on what I might be doing wrong?
