How to put pictures from my iphone in my computer?

So I didn't have photo stream on before and now that I don't have much space i want to delete the photos and put them on my computer and I turned photo stream on but it only syncs the recent photos like the new ones, so how to do I put the old photos on my computer /?!

Email them from your phone to computer or text a pic to your email. Instead of texting a cell number, text an email address. Go to computer and save it from your email.

Plug your cord into the computer and go into the phone through the explorer not through itunes and open up the folders until you see your pictures. Mine only had one folder
