I randomly figured out that I could just click on send, and instead of sending it to a phone number, I changed it from number input to text, and wrote my hotmail email address, an my phone just sent it to my hotmail account.
That's how it works in the UK and Qatar.
Don't know if it will work where you are.
Just open the photo, go to send, enter your email address. See if that works. Obviously, it costs to send a picture message though, it's not free like transferring with a cable, but I don't have the cable either, and had the pictures stuck on my phone for ages, until I randomly tried to email it, and it worked!
