i found one trick is to only select a few at a time. it made a difference at the time i was trying to upload and running in to this problem.

at this point... this resolved itself for me. i haven't seen the error recently, and have selected a whole page to download. i didn't do anything new either, no new update or reboot or nothing. i use this at the office to offload picture i need for listings, so it's frequently used.

maybe it's something with the connection. i still have the feeling like the 'error' wasn't resolved, that it's still a bug i'll stumble on to again. good luck.
having the same problem. when i start the download through windows, it only shows the PNG or XMP format. when i initiate the photo selection through the phone tho, it shows as JPG>ZIP in my windows browser.

any suggestion to make it work through the browser as it's supposed to?
