transferring photos from mac to mobile

Try as I might, I can not arrange photos to my discretion when I transfer them to my iPhone or iPad from iTunes on my Mac. I've tried numbering them the way I want them viewed and I've tried to change the capture time in Photoshop... to no avail.

I know it's possible to organize images on your mobile device when they are in a created folder, but it appears it's impossible to customize their arrangement when transferred from a Mac.

Does anyone know if it's possible to do what I'm attempting?
