IPhone 4s only sends pics to other iPhones that have iMessage?

I can't send pictures to anyone who doesn't have iMessage and it makes me mad because I try to send my dad pictures of like my grades from school but they won't send. My phone is Jailbroken but I don't think that's the problem. Don't tell me to go to settings then his MMS on or whatever it already is and don't tell me to reset the data or whatever. Doesn't work either. I don't want to spend money to get technical support when I don't think it will even work. The guy said if I take the jailbreak off it probably won't even fix it.

Do you have your Data turned on?

If you are using Wi-Fi only you can't send pictures over text message normally, or receive them either
