You should upgrade to the current iOS version (11.2 at this time).
Update the iOS on your iPhone, iPad, or iPod touch - Apple Support
Regarding the "picture in a message", you have not told us if you're talking about an MMS cellular multimedia message or an iMessage to/from another Apple device. These two methods are very different, and would take very different steps to remedy.
MMS would require:
- Settings > Messages > MMS Messaging = "On"
- Your cellular carrier authorizing you to use MMS messaging on your cellular plan. This may cost extra.
