I'd like to know how to add photos to an iOS device without iTunes nor any "iPhone explorer" programs.
I have the image files, and I have the iPhone "mounted" on a Linux machine, which means I have access to some directories like DCIM and PhotoData.
Now, how do I actually put the pictures in ? I tried dropping them in DCIM but of course it doesn't work and despite the files being there they don't show up in the camera roll. Is there any particular thing to do after copying the files, or a particular file name syntax to follow?
