It seems difficult to transfer pictures to the iPad. Sure, I can sync a folder through iTunes but I hardly use iTunes for anything so this is not really convenient, plus, I need to keep a separate folder I sync with the pictures I want on the iPad. I'm not trying to diss iOS here, but on my Android devices I just move a folder over into memory and bam, it appears on my Gallery view. I can even rename files there if I wish to or en-masse create new folders and move files around.
Since Dropbox does not let you DOWNLOAD a whole folder or multiples files at once, using Dropbox to move the pictures I want to the iPad is also not feasible. Hence, I had hoped Photostream could help. So I set it up on Windows 7 machine, pointed it to an upload and download folder and thought I was golden. Put about 30 pictures in there and then fought with it for 30 minutes and the Apple Support Forum to actually make them apear on the iPad. After a Photostream reset they actually did.
Then yesterday my wife moves a bunch of pictures from our camera to the computer and figures she'll drop some new pics in my upload folder so I can get them while at work in Photostream. That didn't happen though. The pictures never got the iPad, though I'm on constant WiFi at work and above 20% battery. Tried resetting Photostream again but no luck. Disabled Photostream and enabled it again; nada.
I hope there is a Google Drive App soon that works, or that Dropbox finally enables you to download whole folders or multiple files to the iPad. I thought iCloud was just supposed to work?!? :-|
