I switched from iOS to Android, and wish to transfer my pictures.
Where on the filesystem should I put the pictures? I first thought /DCIM/camera, but that's the directory for pictures shot with the phone.
/media and /Pictures seem to be appropriate, too.
I just want to set up everything in the best possibly way. I also want the pictures to be in different folders e.g. holidays, work, etc...
I have a Nexus 4 phone, if you need that to help me.

.nomediafile, the media scanner will find and catalogue them, so you apps (like e.g. gallery) will find and show them. On my phones, there was aPhotodirectory on the sdcard. The Nexus 4 not having a card slot, you probably could simply create such a folder on its internal sdcard. – Izzy Dec 23 '12 at 12:37
