Photo transfer Error Message

I get an ERROR message every time I try to transfer photos between my iPhone 4 and iPad 2 or my iPad 2 and my MacBook Pro and it won't download. It doesn't matter if I do it over WiFi or Bluetooth. It connects just fine on all devices but for some reason al my pictures cause error messages to pop up and I have to cancel the transfer.

It started happening after the last update of the App prior to that it worked fine and I heaped praises on your App, now I hurl epitaths for your piece of ..... App.
