In not sure if you guys are having a problem with the IPhone uploading pics with the AG app? Tapatalk is similar to the AG app on the IPhone. On the AG app to add pics:
1. Hit "insert" top right of screen next to "send"
2. Hit "image" pops up after hitting "insert" on bottom of screen
3. Hit "library" (this will bring you to the picture library on the IPhone.
4. Hit "camera roll"
5. Now you will see all your phone store pictures on the IPhone.
6. Touch the picture you want, then center it on the screen with your finger. Then hit "choose"
