Is there a way of syncing all my iPhone photos to my PC, either to a single folder or preferably to folders by location or date?

Most of the photos I have relate to work projects so it would be handy to have them accessible from my PC.

I move all my project related picts to project dirs on my PC, and use a service called Tresorit to sync those dirs with my laptop and engineer's 'puter (she lives in a different country). If I ever need to view the pict again (or any project doc) on the iphone (which is almost never), I use the Tresorit app.

Most of these cloud sync services forces one to put their sync'd dir on the desktop, which I find annoying, any my clients tend toward long dir structures so I don't want to waste 30 odd characters on bla/bla/desktop/bla. Tresorit allows you to have your sync'd dirs anywhere.

It's handy to keep the photos on my phone as if I need them on site they're accessible even without internet.

If I can sync them to my PC I can then put them into Project folders on the server which is backed up, and upload to DropBox for sharing as necessary. This would mean that my photos are safe and accessible wherever I am.

Why not just use icloud then? If you're going to copy them over to the project dirs anyway, you can do that directly from icloud on the web.
