I'm having trouble downloading jpeg files from my Nikon D7100 to my 3rd gen iPad. I see them come up for download and select download and a red exclamation point shows up in the bottome RH corner of the thumbnail instead of the green check
I was able to find two articles that might assist you in troubleshooting the issue:
iPad: Using the iPad Camera Connection Kit
iPad: Using iPad Camera Connector with unsupported USB devices
Hope that helps,
