iOS and iPod: Syncing photos using iTunes
Another way. You can use a USB flash drive & the camera connection kit.
Plug the USB flash drive into your computer & create a new folder titled DCIM. Then put your movie/photo files into the folder. The files must have a filename with exactly 8 characters long (no spaces) plus the file extension (i.e., my-movie.mov; DSCN0164.jpg).
Now plug the flash drive into the iPad using the camera connection kit. Open the Photos app, the movie/photo files should appear & you can import. (You can not export using the camera connection kit.)
Secrets of the iPad Camera Connection Kit
Why should I buy a kit ?
The photos I want to transfer are on my Mac not a digital camera. Did Apple take away the feature of syncing photos from Macs to the devices using iTunes (version 11.0.1) ? Why? This seems odd and defeats the purpose of having syncing as a method of transferring data from computer to device.
